Even when I sing the right words they somehow turn against me. Hammerite & I sing an old Alison Moyet song called Bad Connection - which in the chorus has the line "I've been calling all day". Unfortunately as we sang it I started to hear it as "I've been Colin all day". As mentioned elsewhere, people are not always paying attention - so there were a lot of bewildered faces when I said afterward that I had not in fact been Colin at all that day - Colin himself looked particularly worried...
And then there was the horrible moment when I was singing a wondrously soulful rendition of The Water is Wide, and the entire pub and myself simultaneously noticed the double-entendre inherent in "I put my finger into some soft bush". It was hard to keep a straight face after that. I think I actually blushed..
