Odd--I know a completely different "Footprints on the Dashboard"--it's sung to the tune of She'll Be COming 'Round the Mountain, and the first line is:
"There'll be footprints on the dashboard upside down."
The song I know is much bawdier than the one in the DT, and I'll have to overcome a lot more inhibitions before I'll post it with my name attached to it.--Charlie Baum
