In the early 1950s, there were actually people who took offense at this work.
They believed the original singer, a teenager named Jimmie Boyd, waa watching his mother liplocking some guy who wasn’t his father. For them, it wouldn’t have been a laugh if Daddy had seen what was going on, it would have been a sin.
But, of course, we all know who’s who in this tale, and it’s really just pure, wholesome family fun.
That’s also true when the lyric is changed to “I Saw Daddy Kissing Santa Claus,” as RuPaul and others have famously done.
The definitive version of this song is probably the one by the Jackson 5 in the early ’70s. But I’m more partial to the version by the Ronettes.
