Here's two other vatiations of my husband's and mine:

stella ella ola
chap, chap, chap
singin 's' chiko-chiko
chiko-chiko chap, chap
's' chiko-chiko fallo fallo
fallo fallo fallo
oh 1-2-3-4-5

or

's' tigga tigga
tigga tigga tac toe
's' tigga tigga
tigga tigga tac toe
fallo fallo fallo fallo
fallo fallo

I also wonder what the original is.
