"Rainy Weather Blues" is definitely the title of the B-side according to the record label, not "Rainy Day Blues". I've corrected this, and I've also changed the label to the more widely distributed DeLuxe Records (Linden, N.J.) where this record came out first. Actually it was also released on Roy Milton's Miltone label, as originally entered, but that was a rare license issue of probably several months later. BigBadBluesMan, who claims to own the record, possibly doesn't own it as a physical 78 rpm record (his given source http://www.soulfulkindamusic.net/roybrown.htm lists both Deluxe 3198 and Miltone 3198 anyway). No matter which label, the title of the B-side is always the same.
Roy Brown is distinctly trying to sing above his range throughout Fore Day in The Morning. I get the impression he is trying his best to be Billy Eckstine on this track and he just doesn't have the chops to do it. It would be better if he'd slowed it down and let the band help him out a little more.
Rainy Day/Weather (which is it, guys?) Blues is better because Brown stays in his range most of the time and he does let the band help him out. If he was looking for a model on this one, it ought to have been Louis Prima. (I know, sacrilege.) The similarities of this track to Jump, JIve and Wail in attack, organization and spirit are remarkable. There is, however, a certain disconnect between the overall approach and the subject matter of the song. To me, it's god but not great.
