When you're a new Spoonful fan, sometimes it's a challenge to tell who sang what, especially when you're trying to judge between John and Zal's vocals. (I like to analogize that Zal's voice sounds like John's if he was always yelling.) However, I'm here to help. Here are a list of songs that were sung by Spoons other than John.
Note: That means that all the songs that aren't mentioned here were sung by John Sebastian.
Songs Sung By Zal:
Blues In the Bottle
Alley Oop
On the Road Again
Voodoo In My Basement
Day Blues
Bald Headed Lena
Songs Sung By Joe:
