Bat, a.k.a. Kelly Winrich, is the pianist/percussionist of the band Delta Spirit. Bat joined Delta Spirit in 2007 thus ending his solo career and amalgamating his songs into the Delta Spirit, with lead singer/guitarist Matthew Logan Vasquez becoming the voice of Kelly's songs. Such Delta Spirit songs as 'People come on' and 'wait until tomorrow goes away' are carry over songs from Bat's solo career.
