All the original singers are from Arkansas.

By the way so am I, born and raised in Northwest Arkansas.

OOOOOOOOO this is a REAL BRAIN TEASER...let me think..I'll be back, ok?..hmmmm..crazy and woodburn may be on to something...

a wild guess--The original singers are all from the same state.

Just guessing here,but could it be that Floyd Cramer played piano on all of them?
