Some further notes: There are five samples from three different sources. One of them is somewhat obvious - the other two maybe less so. Try and guess what they are.

The clanging percussion in the bridge is one of those pieces of open metal shelving, typically painted white, that you find in hardware stores. I strummed it, and also hit it with a mallet (then altered the pitch so it's more or less in tune - even though that's actually rather hard to hear). All other noises come from the reliable Yamaha keyboard, except for the syllables, which were tortuously edited from a number of performances and then further mangled with the GoldWave flange-o-matic. I don't think I have any further secrets.
