That answer presents difficulties. I see that there is a YouTube video of Water Music Suite 1, and it's 26 minutes long. And that's just Suite 1.

Trouble is, by the time I listened to all the Water Music, my memory of the theme for the jubilee will have been extinguished by all the new themes from Handel.

I'm pretty sure the Water Music is more complex than the music I heard while waiting for my flight.

Aren't there columnists, critics, spies or sycophants who keep track of everything the BBC does? I hope some body who knows Somebody can find out about that piece of music.
