Susan Boyle both happy, sad at musical based on her life

London: Singer Susan Boyle says watching a musical show based on her life made her feel both sad and happy.

The musical ‘I Dreamed A Dream’ is about the struggle of Boyle, who rose to fame with reality show ‘Britain`s Got Talent’ in 2009.

The role of Boyle, 51, was played by Scottish actress Elaine C. Smith but the former had gone on stage herself most nights to sing the title song.

"It`s funny when you see people playing people who you knew. It`s very surreal. To begin with it was upsetting because I was not used to it. Once I got into it though, it was quite clever and amusing," a website has quoted Boyle as saying.

"It was dead funny seeing Elaine pulling on the wig. I went, `Oh my God, what`s this?`," she added.

The singer says the show, which is currently being staged in Britain, might be taken to Australia but a date has not been fixed.

"I`ve been invited to go along but I don`t know when," she said.
