Joy To The World

It's really easy, the three chords after each line of the verse are just

an A shaped bar chord being slid up the neck.

Joy to the World (Three Dog Night)

Jeremiah was a bullfrog

A very good friend of mine.

I never understood a single word he said

But I helped him to drink his wine

Yes he always had some mighty fine wine

Singing Joy to the World

To all the boys and girls

Joy to the fishes in the deep blue sea

Joy to you and me.
