I was so amused by this thread that I dug out my LP of Jonathan Richman and the Modern Lovers and played the 'Ice Cream Man' song
Thanks john - it is on youtube and after dreadful start, it certainly improves after 3 mins.
The classic Ice Cream Man song is by John Brim recorded in the '50s and made famous by Van Halen. Not a tune likely to be played by an Ice Cream van though.
