Hello, I search for a roll with the German popular salon-music-tune,
"Was machst du mit dem Knie lieber Hans", for any 88-note system.

Can anybody help me?

Wolfgang Heisig

 [ Hallo Wolfgang von Leipzig !  This seems to be a humorous song --

 [   "Whatcha doing with your knee, Dear Hans?"

 [ it's even possible that the QRS company made a music roll.
 [ I hope that we can help you !  :)  -- Robbie
