OK, you know the song 'Killer Queen' (by Queen)? There is a line in the refrain 'Wanna try'.
Well, when I was very young and first heard this song, I thought it said 'What a drag' as in how boring.....of course, when I was older I held onto my version because it then seemed to make perfect sense that the song was about a drag queen.
I was only enlightened a few days ago - oops!
