We used to sing "Skip to my Lou" in the "Idle Fellows" and I still sing it a fair bit myself because it goes down well with German audiences on account of the easy chorus (there are only five simple every-day English words in it!. The version I sing can be found in Lieder, Songs und Gospels 3.
A more difficult version can be found in Folks & Blues Spielheft 1 which has a rumba-style accompaniment.
