Roadie Rocks Out When Bassist Passes Out

A roadie for the Gin Blossoms got the opportunity of lifetime at Summerfest this week -- when bassist Bill Leen passed out cold during the last song of their set.

We're told the band finished the song with their new bassist while Bill just laid there -- and then the roadie came back out for the encore performance of "Follow You Down."

Not that far ...
