For Collectors Only is the best compilation available for the Cadillacs, having the edge over the single disc one on Rhino. Every song on that compilation is collected here, along with quite a few excellent tracks that didn't make it on. I will review some of those. Buzz Buzz Buzz, featuring energetic vocals, "King Bee" styled guitar and fine production arguably betters the Hollywood Flames version. Shock-A-Doo and If You Want to Be a Woman of Mine are very catchy up-tempo rockers.The ballad Carelessly has a mysterious beginning in the voices, and could be compared to Window Lady and Gloria in its use of the organ. Also great is the raucous Holy Smoke Baby, with hilarious lyrics and screaming vocals reminiscent of Little Richard. There are plenty of other small pleasures on this set, although every track is not of a uniformly high quality. Still, I would say the Cadillacs may deserve a spot near the end of the top ten list for best R&B vocal groups of all time. Despite having only two big hits, they recorded alot of material in their day. Unfortunately, there are no recording dates, personnel, or other valuable information. In buying this set, you are getting 60 tracks, (three and a half times more than the single disc collection), for only about twice the money. I recommend buying this, because the gems on this set missing from the single disc are just too good to overlook.
