My old Pop (very old!) says that it is a song he remembers being sung by Arthur Askey in the late fifties or early sixties with a female singer possibly called Yana and he thinks it went 'yada, yada, yada, yada, ching, ching, boom' at a faster pace than the commercial.

However an intensive websearch is, so far, unrevealing.
