Singer Ashlee Simpson may never live down her microphone malfunction last October on "Saturday Night Live."

The embarassing screw-up had Jessica Simpson's younger sister running off stage after a production problem caught her lip-syncing the wrong song -- and she will always be remembered as the one who got caught.

Simpson was supposed to debut the song "Autobiography," from the current album of the same title, but someone replayed her previous "SNL" song, "Pieces of Me," catching Simpson completely off guard.

The 19-year-old singer drew withering attacks from media and fans. There's still a "Stop Ashlee Simpson" online petition addressed to Geffen/DGC Records and JT Simpson Entertainment that begins, "We, the undersigned, are disgusted with Ashlee Simpson's horrible singing and hereby ask her to stop. Stop recording, touring, modeling and performing. We do not wish to see her again."

It's sad in light of Simpson's admiration for such singers as Janis Joplin, Stevie Nicks, Pat Benatar and Chrissie Hynde. But with hard work, Simpson may overcome the "SNL" debacle.

Simpson is back on the road with her hard-edged pop-rock, performing Thursday at the Paramount Theatre, with opening act The Click Five, a power-pop group of five young men from the Berklee College of Music.
