Angie Bemiss has an arrangement for “Sunrise, Sunset” in her book Unforgettable Theatre Treasures available at Melody Folk Harp http://www.folkharp.com. You may be able to get it as a single copy if you contact Angie Bemiss. Her book is good to have for gigs.
If you have a Kindle app and an amazon.com account you can instantly buy the digital version of “100 Best Loved Piano Solos / Big Note (Big Note Piano Solos)” [Kindle Edition] with arrangements by Robert Schultz for $9.99.
This book contains several pieces from “Fiddler”, including
Matchmaker, Sabbath Prayer, Sunrise,Sunset, To Life, and Tradition,
in big-note easy piano arrangements which unfortunately do NOT include lyrics or chord symbols. These arrangements are not quickly adaptable to lever harp because of numerous accidentals, but could be adapted for pedal harp by a non-beginner harpist.
So “If I were a Rich Man” isn’t featured ? It used to annoy me but now I like it although it’s probably too chromatic, like Take 5, but it might be fun to include it in a medley, I’ll try to play it by ear on the piano first……
