Feargal Sharkey and Cyanide

I have had Feargal Sharkey in my head for twenty three and a half hours now. Its not that I'm dismissing his talent, I was quite partial to a bit of Sharkey on the dance floor of my school disco - the one's that started at 5.30pm and ended at 8.00pm, it could've been worse, I went to a lunchtime disco once and they didn't even turn the lights off - however I wish there was a pill, other than Cyanide, that wipes a song from your brain. I once had "Happy Birthday" in my head or a whole weekend once. It wasn't even my birthday, or anyone else's, and when it got to the bit in the song where you sing the name it was just a lazy hum, like the battery cut out for a couple of seconds. Somebody once told me that the only way to get a song out of your head is to play it, three times back to back. I am actually going to kill that person. With Cyanide.
