Without much practice, I sang with the band while trying to play again last night. Wasn't good. However, towards the end of our session, the drummer and bassist started screwing around with a groove that sounded like "Feliz Navidad" so just to screw around with them I walked up to the mic and started belting out "I WANNA WISH YOU A MERRY CHRISTMAS!!!" - I guess I found my range with that and the guys stopped and wanted to work on the real thing with me singing. It was really cool to be a vocalist for a change. Gonna have to work on this because it's incredibly satisfying.
