I said to my two young men, "This was originally sung by somebody else, do you know who it was?"
The eldest (12) said, "Was it that guy with no shirt?"
"That's right," I said, "What was his name?"
"I'll give you a clue. His first name was Freddie and his second name is also the name of a planet."
The younger (7) thinks a bit then pipes up...
"Was it 'Freddie Uranus'?"
I think Freddie might have quite liked that.
