I love that song and it sometimes feels like it was written for me . I know ... stupid , but i connect with it well . There were some drunk chicks dancing and singing way out of time and tune and was glad they only did it at the end and left early . The last thing they did with the monitor thing was like a wheel of fortune thing , someone came out , i think it was the drummer , but i ' m not sure because it was dark except the screen , and pushed the buttons to change them in beat with the song . It was nt one that i recognized , but it was still cool . The concert was just really amazing .
According to the above context, answer the following question.
Why was the drummer the person that came out to change buttons ?


He was the person most familiar with the machine .
