A friend of mine, who is a big fan of the rock band R.E.M. was telling me that he had managed to get tickets to see the band and also got backstage passes to meet the band, after their performance.
He showed me a few photos taken with the band pointed and said "that's me in the corner"
You actually need to know some of the lyrics to their songs, Baz. Otherwise you've as much chance of 'getting' the joke as you have of seeing the man in the moon.
