It's in DigiTrad--search for Wanderin* (the asterisk will find it with or without the final g)

I have a personal history with this song. In nineteen ought forty-eight, I was working with a band (square dance mostly) which called itself The Wanderers, and used Wanderin* as a signature tune. Then Sammy Kaye (SWING AND SWAY WITH...)made a hit recording of it, effectively forcing us to find a new theme tune. WE picked up a little-known waltz, and used it as a good-night waltz. Catchy tune...Irene Goodnight.

Oh well.
