Live music at the actual jubilee is irrelevant.

This was a charming, recorded piece which they played on the telly whenever they ran out of breath (silence being anathema). It could be heard again and again.   

Someone just might have recognized it or seen a credit.

YouTube: have you seen the number of YouTubes about the jubilee? I couldn't possibly listen to them all.   

This piece could finally replace Mouret's Rondeau as the one baroque piece the general public can recognize.
