"An old guy came up and said "Play Somethin'". I did what I thought was a great tune (Song for My Father, I think). He came back and said "Play Somethin". I kept "upping the ante", playing the best I had, and he still came up and said "Play Somethin". Turned out he wanted me to play "Something", the Beatles tune.

Russ, I had that same thing happen recently. I finished a song and a guy called out "More!", so I did another chorus. When I finished he yelled the same thing again, so I did a similar song. The third time he came up to the bandstand and said "don't you know More?" It finally sank in and I played "More". Just to top it off, when I finished, he called out More!
