I was really impressed with thier timing... anyone who has ever done this type of performance knows timing is the key factor and maintaining it.... When i was in High School ( many many moons ago) I was a Percussionist. I Teacher and Field Major always informed the rest of the band to listen to the Percussionists to maintain count and timing... OHHHH the fun the other percussionists and I had with this.. we would sometimes deliberately go off beat to see who was listening to us.. I think the Liberty High Percussion Group was in better shape and logged more miles than thier Track Team.. LOL The two songs we always got them on.. Pink Panter Theme and intro to Centerfold by J. Giels Band.
