I'm thinking it might be called Hey! Cousin Rainbow but I've never been able to find it or who did it to search further...I taped it off a very late radio show in the late 60's and have always wanted to get a better copy of it...Hoping this is the place to finally find out...

Hey Cousin Rainbow (all around)
Hey Cousin Rainbow (should be found, all around)

Hey Cousin Rainbow,
She doesn't love me, dunno why
Hey Cousin Rainbow, doncha cry
I'm for you, doncha know, doncha know
I'm for you, doncha know, doncha know

There's no use cryin
Just stop your lyin'
You must make up your mind
Heeey, don't you cry

Hey Cousin Rainbow,
She doesn't love me
I really loved her
I want to know now
Hey Cousin Rainbow, by my side
Doncha cry
Hey Cousin Rainbow
Hey Cousin Rainbow doncha know, doncha know
Doncha know, doncha know, doncha know...
