You and Bryan Adams. He arranged his European tours around the British summer months when the ice cream vans play their jangling tunes. His record company blocked him covering The Teddy Bears' Picnic and were dubious about an original song he wrote called Stop Me and Buy One but they were oblivious to his sneaky trick. Listen very carefully to the fade-out of Summer of '69 and you can just hear him sing "Me and my baby had a 99", a reference to the Cadbury's Flake + ice cream cone combo. I thought he referred to another number until I found out about his fixation for a scoop of Roskilly's.
Not music related, but a '69' was when you put the flake up through the bottom of the cone. It didn't catch on as it tends to fall out.
