The ice-cream van of my childhood played a tinklified variation of Harry Lime's theme
In Henley we were treated to The Great Escape
In Chatham the office sandwich van played Eye of the Tiger and my current sandwich van plays La Cucuracha. I have never been enticed to buy either an ice cream or a sandwich from any of these, but I do appreciate a better class of theme-tune.
It seems that Mike is my local door-to-door ice-cream.
He played a familiar folk-Jig that I can't put my finger on. I hope we have a hot summer and that I get to know him. I imagine he has Italian heritage, though I expect the ice-cream contains the usual crap. I'll update you when I find out more.
