Probably, but I still wouldn't have to listen to that musician if I didn't want to, this being a free country and all. The problem with Government and Religion is that in the United States and other countries the Government should be representative of all the citizens. Well the last time I checked, at least in the U.S., a large majority, something like 85 or 90% described themselves as religious, even if they didn't identify with a particular religion. At the same time, the remainder can't be left out in the cold either, so the happy medium is to have government be kept separate from religion, neither promoting any particular faith or denomination or religion in general, but also not disallowing it's practice through overt action. Which is in the Constitution somewhere and is what Jefferson meant in his Federalist Paper on the subject(#78 IIRC).
The issue is arising because a very vocal minority, who I will remind you isn't being harmed in any direct or indirect manner by the allowance of prayer, has decided to use Governmental power to force the disallowing of something they don't like, in this case prayer and the practice of religion in general. In my view this would be analogous to the banning of public displays of affection such as hugging and kissing, as someone who has never had a girlfriend or other intimate companion I am uncomfortable with public displays of affection, but I am in the vast minority, so even if I find it uncomfortable, my participation in the event as a minority is to either admire it or ignore it and move on with my life as it has neither harmed me or benefited me in any way.
I'm trying to not sound like what most of you would call a fundie whacko.
