This is my son Alex proposing to his girlfriend Suzanna on stage. She is the Choir Director at a High School, and this occurred right after intermission at her concert. She had no idea. My son is a former professional actor/singer/model, but they are moving to California for his fellowship at UCLA where he is completing his PhD in Molecular Biology. I hope at least one of the links I have shared below allow you to see this. I think one link is the lead up, and the second is the song/proposal.
