Open day performance last class

Last class which was on Wednesday,What happened was that some of the students were absent due to Acting performances etc.So what Philip did was that,he split all the girls in one group and the boys in one group and went to our respective rooms for practicing,As the teacher(Philip)said that we were going to perform on the open day at 4pm. So the girls were preparing one song with the backing track and the song which they had actually performed was one of the songs in which one of the girls in our class sang that particular song,It must have been Isabella if I am right or wrong.They performed with the backing track.

And we as the boys sang don't stop believing by journey and we made a group band.I was the singer,David was playing the bass and singing a little bit,Robert was playing the piano and Tone was playing the drums.The performance went Ok,We kept practicing in the individual performance rooms,And then finally we did a sound check at 4pm and performed in front of Philip,I sang the words clearly in the first performance during sound check and in the second time of performance for the actual open day on Wednesday,nobody came for the open day,So we again gave our final performance and I messed up  a little bit in the second part of the song because the tuning of structure
was the same for the three verses,but the lyrics were different in the second one.This gives a basic Idea about the music ensemble which is the next assignment we are going to work on.Now I have already got my actual group for the ensemble assignment and will work well to perform better and especially learn well individually and with the group of what songs we are going to select in order to make a better performance.
