Last night I tried to sing Stand By Me (the Ben E. King version) and... flubbed it. I mean completely, savagely destroyed it. I couldn't find the right key to save my life - I was stuck somewhere between the King version and Lennon's version, and actually had to bail on it and try the Lennon version instead, which I made it through OK despite being way more familiar with the lyrics and rhythm of King's.
It's been a long, long time since that's happened to me behind a mic. Bah. Fuck humility. Fuck it in its stupid ass.
