I believe the reality is that Elvis's dad wrote teh jingle rather than sang it in the ad?
Ross McManus - Elvis Costello's dad - both wrote and sang "Secret Lemonade Drinker", so the orginal comment that he appeared in the ad is kind of true. But he wasn't the actor raiding the fridge - who was miming.
For the record, young Declan McManus, who would later become Elvis Costello, sings the backing vocals (the "R Whites.... R Whites..." bit). Rumour has it he also played the drums on it.
For really useless, non-musical, and slightly dull R Whites trivia, but with a Sussex connection, the house in Rustington my dad lived in from '78-'93 was originally custom-built for the then-owner of R Whites sometime in the late 1930s...
