Choral Choir (SAB) - Level 3 - Digital Download SKU: A0.919597 By Smash Mouth. By Neil Diamond. Arranged by C. Alex Luke. A Cappella,Pop. Octavo. 13 pages. C. Alex Luke #3584835. Published by C. Alex Luke (A0.919597). This is an arrangement of The Monkees  hit I'm a Believer (featured in the motion picture Shrek) for a middle school or high school a cappella group. While a male soloist is featured throughout, the limited range for the guys' part allows this to be performed by a group with a smaller number of men. Add some vocal percussion (a suggested rhythm is notated) and this will really shine!
