That boy and the girl that could sing

"Thank you all so much for listening to our very first concert! My crew and I enjoyed it here and we hold you did too. Thank you so much and goodbye everyone!" The lead singer said, walking off the stage and waving at the crowd.

A group of boys were walking past the performance and one of the boys got the song stuck in his head and started humming the tune of it.

Is something going to happen with this boy and the band or is it all just a coincidence??
