First of all they kept great contact throughout. Also they had to drive 10 hours in the snow and still arrived on time. They were professional enough to ask if they should still play a song that had foul language in it due to children being present. They were accomodating, professional, and INCREDIBLE as far as talent and presentation. The show rocked, their outfits and appearance were identical to the real "Glimmer Twins"(Mick Jagger/Keith Richards), and I gave them a 20% tip due to my extreme SATISFACTION!
