I remember seeing the couple at “The Theater In The Round” in Houston in the late 70s.
Steve sang a very slow ballad then Edie did a very jazzy “It Had To Be You”!
After Edie sang Steve went on-and-on about “How come I have to sing a slow ballad and YOU get to sing a jazz number that had the whole place rockin’?’
They had the whole place ROFL with their humorous give-and-take.
They don’t make that kind of entertainment anymore.
In fact, other than Steve and Eydie and George and Gracie, can anybody else point to a husband and wife entertainment team nowadays? ( Jay-Z and Beyonce perhaps? <-— But I don’t see them performing together )
