When Charles first started this collection, he didn't include the verses on a lot of songs, so he has added four volumes of songs to make up for that omission:
Verses-Chorus Volume #1 Pgs. 1-230 315 songs $18.40
Verses-Chorus Volume #2 231-452 273 songs *17.76
Verses-Chorus Volume #3 453-621 205 songs 13.44
Verses-Chorus Volume #4 622-859 275 songs 19.04

The ENTIRE SET of four volumes, 858 pages, 1068 songs is $ 68.64
