Tracy Bonham performs “Big Red Heart” from Masts of Manhatta on Tonight Show 7/12/10

On Monday’s Tonight Show with Jay Leno, Tracy Bonham performed “Big Red Heart” from her new album, Masts of Manhatta, available now.

Rockin’ cowbell performed by L.A.’s own Rich Ferguson, spoken word poet and long-time contributor to The Nervous Breakdown.

We wonder if Christopher Walken loves this number as much as we do — because, you know, he has a fever, and the only prescription is MORE COWBELL!
