I remember one night..while working with one of my favorite girls..A fellow came up to the stage and placed $100 bill on my keyboard...requesting an old standard..
Kath didn't know the tune..I played it thru one time...Then we went on to another song (same feel)..she sang the second tune..and I closed it out with the last verse of the requested tune...At the break the fella was so happy..we filled his request...Sorta..

True story...
