FMP-Cut of Songs for the Gig

Olly,who is my Musical band workshop teacher has Said that we can't perform Castle of Glass by Linkin park because it was not rehearsed with the full band being present like Kessanna didn't show up for the performance for run through on Monday,Only Wavin Flag and American Boy can be performed but it needs to be rehearsed with the the full band being present on the Day of the Gig and also for the Upcoming rehearsals and when we book access time on Friday.I kept telling my Band members to rehearse and they should now at least rehearse these two songs and then it should be well rehearsed by all of us and perform better in the Gig.
