The arrangement is for a co-ed group. There are four principal background parts (standard SATB) in addition to the solo and two secondary solo lines. Hand percussion in addition to VP adds context to the song once you get into the second verse and three part round. The parts are fairly simplistic but create contrast when put together. I would say it is easy to learn. It all depends on what you do with it. The piece was arranged for a co-ed college group, but it also used by adult groups, high schools, and various summer programs. The arrangement is sent via email and comes in pdf, midi, and/or .mus (finale). Materials, shipping and handling are extra for CDs, and hard copies (all purchases of the song have been made electronically). Please let me know if you would like any additional information! The arrangement has been well received by all who have used it. I love the song personally, and it's a crowd favorite.
