I remember hearing once that the noun form of dawn was first used by Shakespeare in one of his plays. I can't find any information online that would directly supports this. I can only find indirect support with Online Etymology stating that the noun version was first recorded in 1599. Does anyone else know anything about this?
I would like to point out that there have been two historical defenestrations of Prague. It is quite possible that certain groups of people are more prone to throwing other groups of people out of windows.
Try to find the recording by Frans Brüggen and the Orchestra of the 18th Century (on Glossa, a Spanish label, GCD921101). They're a period instrument orchestra (a lot of modern orchestras will substitute tuba for the ophicleide and it's not quite the same; also Brüggen's recording is really good!).
For nothing but solo ophicleide try: "Back From Oblivion" on the Australian label Melba (301111, available in the States and elsewhere, try arkivmusic.com). The player is Nick Byrne, a Sydney boy.
