The bass is so much fun but I realized that my body can't multi-task; that is to say, I can't sing and play an instrument at the same time. Singing and playing the tambourine? Impossible. :( So props out there for all the singer/guitarists/pianists out there.
Anyway, Vic loves to quote this when we talk about the bass, from the movie I Love You, Man. It really starts around the 0:14 mark or so. Enjoy!
