Well your absolutely correct, except more like 80% of the show was music Reagan had done before due to Guidry doing their music as well.
Broken's Arrow's show where former Reagan was played:
9:00-9:20 9:55-10:36: Reagan 2002 Closer
1:50-2:20 3:20-4:05 4:45-5:00 7:45-8:30: Reagan 2004, nearly identical to intro in music and some similarities in drill as well
6:40-7:40: Reagan 2005 Trumpet solo
