Amy Winehouse's unexpected curtain call last month was every musician's worst nightmare. The 27-year-old singer was caught on tape falling apart on stage in Belgrade in Serbia. She took the stage an hour late in the Serbian capital, appeared to be wobbling around while she mostly spoke to the audience, and couldn't really sing along with her own songs.
The subpar performance required a lot of help from the audience and Winehouse's back-up singers for the star to get the lyrics of her songs out.
The cast of Fox musical comedy Glee, along with celebrities, Ashton Kutcher, Demi Moore and Katy Perry, have paid tribute to the late Amy Winehouse in many ways, in particular, through their tweets on the social media Web site, Twitter.
