Les Waas, an old school jingle writer wrote the most familiar tune anybody who grew up within ear shot of a Mister Softee truck will ever hear. He just died at age 94.

According to Eater, Waas’s distinct jingle could be heard blaring from 1,000 trucks during its peak in the 1960s. Today, there are 600 Mister Softee trucks operating in 15 states — not just in the northeast — and that song still plays, despite an ill-fated attempt to silence it in New York.

Give a listen and smile.
