My father and stepmother moved to Loveland, Colorado after he retired. He sings Barbershop, so he joined the Valentine City Chorus. Every year on Valentines Day, they get a ton of singing valentine requests, most of which are done by the quartets organized within the Chorus.

Dad's quartet did a singing valentine that got posted to youtube a while back: https://www.youtube.com/watch?v=YF48Y4FuyTwJ He's the baritone at stage right (that's the left side of the screen, for the non-actors out there).

The Loveland post office also does what you describe for Valentine's Day. One of the very few valentines done by the entire Chorus is a short concert for the herd of volunteers they bring in every year to handle the huge work load.
