These changes are very useful for lots of songs, especially old pop songs and R&R songs from the fifties.
Try Ricky Nelson's Poor Little Fool
26 Miles Across The Sea
Blue Moon
Heart & Soul
In the fifties a cousin left her ukulele at our house and I learned Frog Went A-Courtin', a tune my dad used to sing to us. Dad sang a different ending that I've never heard anyone else do:
They paddled off across the lake, uh huh,
They paddled off across the lake, uh huh,
They paddled off across the lake
And got swallered up by a big black snake, uh huh, uh huh, uh huh.
That was the end of him and her, uh huh,
That was the end of him and her, uh huh,
That was the end of him and her,
Now we won't have tadpoles covered in fur, uh huh, uh huh, uh huh.
