It really depends on what your state association wants you to do. In my neck of the woods the away team plays prior to the contest and the home band plays at halftime.

We know an R who once intervened. I forget whether he made the band get off the field or threw a flag for the home team not being on the field on time. He received a "memo" from the state who didn't approve of him "bleeping with the band" as he says it.

Now I did once have a homecoming last 30 minutes while I worked as the clock operator. Again, the R used good judgement in not lousing up the homecoming activities but he definitely reported this to the state association who took action. I was the R in a subsequent year and was firm with the AD prior to the contest that he needed to get everyone off the field within the 20-minute timeframe.

Now if one of the teams decide to make a "grand entrance" into the stadium 10 minutes after they were ordered onto the field, then it's an unsportsmanlike foul against that team.
