Donovan left Neighbours in 1989. Twenty years later, he said that he had been asked to return to tie in with the show's 25th anniversary in 2010, but was unable to do so due to other work commitments.
His next single, "Too Many Broken Hearts", reached number one in the UK in March 1989. He released his début album, Ten Good Reasons, in May 1989, which also reached number one (for three weeks). For two weeks, Donovan held the number one positions in the singles chart and the albums chart simultaneously, when his next single, a cover of Brian Hyland's "Sealed With a Kiss", entered the UK charts at number one.
In December 1989, he took part in Band Aid II's version of "Do They Know it's Christmas", which also included Minogue, whose exit from Neighbours had by now been shown on screen in both Australia and the UK. His own exit from the show had by this stage been shown on Australian television, although it was not aired on British television until several months later.
