Lyrics:

Hi everybody, we're the Nazz from Philadelphia, home of tuna fish hoagie. In
Philadelphia, we do a little thing called the loosen up. It goes like this.
First we loosen up on the drums. OK, now we loosen up on the bass. All right
let the guitar player fall in. Now then, now then, the organ player. Get
loose everybody. Do the loosen up. You can do it now. Ain't nothing to it
now. Loosen up baby. Get loose. Hang loose baby. Hang loose mother. Hang
loose fungo bat.
