Recognizing the tune before anyone started to sing, Sarah smiled as she continued to search, but the singing itself drew her attention away from that briefly. Tapping her toe to it at first, the enthusiasm was quickly infectious and she left off her search for a song to sing along, even joining in when those closer to the stage started to clap in time with the tune. Far from passive, her participation along with the crowd was spirited, as it was a hard song to resist, especially when everyone around her was clearly enjoying the performance just as much.
