The musical entertainment is a DJ. I am not sure of all the decision-making behind the DJ choice, but I believe it was motivated by wanting everyone to be able to enjoy the reunion and not be impressed into labor while the rest of us were off having a good time and catching up with each other.

As for staying away from the reunion because your grass doesn't look as green as another's, I think that would be a real shame. I read a book called As a Man Thinketh and found that it contained lots of wisdom that has had a profound influence on me over the years. (That link contains the full text of the book). I forget it occasionally so I have to go back and re-read the book, because it's very natural to look upon situations in life as being unfair. One of the profound messages of the book is that a happy person is not a person in a certain set of circumstances, but rather a person with a certain set of attitudes.
