Okay, this is pointless, but very, very Scottish.  :)

For St Andrew's day, I've made a can of Irn-Bru -- the best-selling soft drink in Scotland -- play the Scottish national anthem. Here's what it sounds like:


For those of you who really can't get enough of drinks containers playing national anthems, I've also done:

The programming is trivial. It's just the RTTTL example from the Tone library, with RTTTL generated from a midi file sent through the converter here: http://midi.mathewvp.com/midi2RTTL.htm.

The wiring is also trivial: just a flat piezo element wired between port 13 and ground. Fixing the piezo to the container can be tricky. For metal cans, a tiny drop of cyanoacrylate will do. For paper cups, a clear glue, applied liberally and allowed to dry, seems to be reliable.
