Talk about superposition

So, apparently, last Friday night was really and truly impressive. If all sources are to believed, I should have been simultaneously at Opening Night at Tanglewood, participating as a supernumerary voice for a choral workshop for high school students, and singing Beethoven's Ninth with the Boston Landmarks Orchestra.

Somehow, this seems like a gross violation of the quantum superposition principle--not to mention the fact that I don't think I can simultaneously sing two notes at once.

It led a few people to remark "he must be really busy." I am--but not with any of that stuff!

[Now this would definitely qualify as an example of omnipresence.]
