"Best decision EVER.  Anyone who's been to a good party knows it's all about the music...we had multi-generations attend and everyone loved the music, even my teenagers.  I literally could write an essay on how amazing, appreciative and talented Cosmo Alleycats are, I'd hire them again without fail and my only regret is that I should have had them play for 5 more hours."
