The first line-up recorded the single “D For Desire” in 1985, but following disagreements around artistic direction between Zwingmann and Regan, the former left the band. Soon after this, Andy Cousin replaced Jackson on bass, thus creating the first well-known All About Eve line-up of Bricheno, Cousin and Regan, plus a drum machine. The group recorded demos and played several gigs.

In 1986, Regan met ex-The Sisters of Mercy guitarist Wayne Hussey. Hussey was then recording the first Mission album God’s Own Medicine and was so impressed with Regan’s voice that he asked her to contribute backing vocals to the song “Severina”. This started a close collaboration between the two bands that continues to this day, and at the time got All About Eve signed to the Mission’s record label (on the back of them being support to the Mission’s first tour and Regan appearing on several TV programmes with the Mission for performances of “Severina”). Regan also provides backing vocals on The Mission song “Tomorrow Never Knows” and “Wishing Well”, which appears on the US version of their early songs collection album The First Chapter. A full-time drummer Mark Price was recruited to All About Eve in 1988.

Following a now-infamous appearance on the BBC television music programme Top of the Pops in July 1988, All About Eve soon hit the big-time with the first album and the single “Martha’s Harbour” peaking within the top ten of the UK Albums Chart and UK Singles Chart respectively, along with four other top forty hits on the latter chart between the summers of 1988 and 1989.

Touched By Jesus did not quite enjoy the commercial success of the first two albums and All About Eve subsequently changed record labels to MCA in 1992. Here they were to record their fourth (and final) studio album Ultraviolet – a somewhat psychedelic move in which, as Regan later admitted, her vocals were mixed too far down into the swirling guitars, with the net result sounding something akin to Cranes or Spiritualized. This alienated fans, and the record did not make the Top 40. MCA dropped the band from their contract.

Revolving around a central core of Regan, Tim McTighe, former Levitation member Christian Hayes (aka ‘Bic’) and original All About Eve drummer Mark Price, Mice released their first single, “Mat’s Prozac”, in November 1995, which charted in the UK. This was followed by a second UK charting EP single “The Milkman” released in April 1996 with the Lynsey De Paul song Martian Man. Countrywide touring followed as did an album Because I Can recorded for indie label Permanent Records. Many collaborators took part in this band, including both Marty Willson-Piper and Andy Cousin which led to people questioning why this band was not launched as another incarnation of All About Eve. Regan said that this was deliberate in that she had wanted the new band to be just that. Musically, it did indeed sound somewhat harsher than All About Eve and Regan would later say of it, “It showed that I could be pre-raphaelitic but I still had to get on the bus and go to Tesco’s.” With Because I Can making the Indie Top Ten, the future began to look fairly positive for Mice, but Permanent Records went out of business in 1997, owing Regan (and others) a lot of money and leaving the album and the three singles “Mat’s Prozac”, “The Milkman” and “Dear Sir” hanging in the shops without promotion or replacement.

Jules et Jim is a collaboration between Regan and Jean-Marc Lederman (formerly of The Weathermen and Gene Loves Jezebel). In 1999 they released a single, “Swimming”, followed by a six-track EP, Subtitles in 2002. Regan also featured on Lederman’s soundtracks for the computer games Fairies and Mystic Inn by Funpause, and Rock Legend by Positech; and also vocals on a number of tracks on Lederman’s La Femme Verte album project.

Despite having previously been on public record expressing absolutely no wish to resurrect All About Eve, in late 1999 a Mission re-launch was underway and lead singer Hussey – in a repeat of the first time All About Eve had become successful – again asked Regan if she would like to support him on tour. Although she was already involved with Jules et Jim (who had put out an EP called Swimming earlier that year), Regan acquiesced, rounded up Price, Cousin and Wilson-Piper, and All About Eve were back (for full details see Recent times).

When asked in 2001 why she had had a change of heart in terms of resurrecting All About Eve and their music, she replied:

Although material for a fifth full All About Eve album had been worked on by Regan and fellow band-member Andy Cousin, it seemed unlikely that this album will be completed. In April 2009, Regan stated on her Facebook page:

Regan graduated in 2014 from Bath Spa University in Bath, Somerset with a master’s degree in Songwriting. As of 2016, she is a lecturer on the BA Commercial Music programme and MA Songwriting at the university’s College of Liberal Arts.
