Choral Choir (SATB divisi) - Level 4 - Digital Download SKU: A0.877199 By Boston. By Brad Delp, Jerry Green, and Tom Scholz. Arranged by Iain Hallam. A Cappella,Rock. Octavo. 16 pages. Iain Hallam #6116929. Published by Iain Hallam (A0.877199). It's a driving a cappella song with contemplative interlude; a huge favourite for singers and audiences. Sing with a large group for lush harmonies, or a tight octet on-mics for power. Some tricky individual runs in the harmony parts need practice to get the lines just right, but the reward is the sound of eight part 80s rock.
