Keith Moon stories are the best stories. (Sorry, I don’t make the rules.) Mick Jagger, unsurprisingly, has quite the Moon the Loon anecdote.

Jagger recalled in a new interview, “Keith was a complete lunatic. I was in Los Angeles in a hotel once and I was asleep, and he broke into my room dressed as Batman. I woke up and there was Batman in front of me, complete with a mask and everything. It’s not quite what you expect in the middle of the night.”

Jagger was, understandably, taken aback by the whole ordeal and mentioned he was, in fact, armed with “some sort of defensive weapon.” Once Moon realized his well-being was in danger, he tried to defuse the situation by telling Jagger, “It’s Keith! It’s Keith!” However, this created confusion, because Jagger thought Batman meant Keith Richards.

“I said, ‘You’re not Keith; I can tell you’re not Keith by your voice.’ [He said] ‘No, Keith Moon, Keith Moon!’ and he took his mask off,” said Jagger.

It’s a good thing Moon removed his mask before Jagger attacked him. Hopefully, he learned to break into hotel rooms unmasked from then on.
