Question:

What are some good yet easy piano solos for an induction ceremony?

I'm playing while everyone is being seated and during the actual induction (something soft). I currently have Largo and Prelude in C Major. Any classical or pop that's easy to learn would be great!

Best Answer - Chosen by Asker: " As Time Goes By " - from Casablanca

Broadway songs from Oklahoma - played softly

Broadway songs from South Pacific - always enjoyable.
