In Britain in the ’70s and ’80s, there was a wildly popular TV commercial (or, strictly speaking, advert) for R. White’s Lemonade featuring the Secret Lemonade Drinker, a guy who crept downstairs to drink lemonade in the dead of night. See it here:

Secret Lemonade Drinker

Did you know? The jingle, which to me was an immediate earworm, was sung by Ross MacManus — Elvis Costello’s father. The backing vocals were sung by a teenage Elvis Costello, not yet famous and known simply as Declan MacManus.

There are those who say Elvis Costello got his early look from Buddy Holly, but it’s plain to me that he was in fact channeling the Secret Lemonade Drinker.
