I agree, Lucy25. plus, you want to beat them at their best, not when they lose a star player. (Conversly, if you lose, you don't want to lose to them without their star player. )
I was at the Detroit Symphony Orchestra concert last night (side note, they played Bolero and I could see Torvill and Dean skating to it in my mind's eye ), and at the very end of the concert the orchestra played Go Get 'Em Tigers and the audience sung the refrain. It was pretty fun.
