Hey there - yes that's the song, but be careful - the beginning "Hey Ho" . . . actually is a fragment of another song. But A-Soulin' talks about Soul Cakes which seem to be similar to the "deadheads" that some South/Central American people make (as does my friend Mary) for All Soul's night/Day of the Dead.
It's totall disconnected from Yuletide though there are definately similarities to the festivities.
