An offering for Roger! Here is “Adagio and Allegro for Piano and Horn”, by Robert Schumann.
What’s the relevance to Roger? Look at the opus number. Happy birthday to one of the finer folks I’ve met online!
(BTW, I actually did a Google search for “List of Opus 71s”, and Wikipedia actually does this! Here’s a handy list of Opuses 70. I thought about the Prokofiev, but it’s late in the day as I’m getting around to this, that piece is 35 minutes, and I don’t like to post stuff without hearing it at least once, so the Schumann will have to do.)
