Gin Blossoms guitarist Bill Leen collapsed during a performance Friday night at the Paramount, MSNBC reported.
The band was playing "Hey Jealousy" when the wobbly-looking bassist fell to the ground. He was helped back to his feet by a stagehand as the song ended.
According to the TMZ website, the 50-year-old refused further medical attention and a representative for the group has since put the health scare down to "exhaustion from the road."
The rocker bounced back and was back onstage the following night at The Stone Pony in Asbury Park, N.J.
A concertgoer captured the collapse from a balcony and the video was posted to Youtube.
