Samuel Black - born 2nd June, 1932 (Paterson, New Jersey) - he had several hits during 1959/60, produced by Leiber & Stoller, with revivals of old songs including 'Lavender-Blue' & 'Always' (he didn't get a mention in Leiber & Stoller's autobiography).
'Raincoat in the River' (1961) - his best record I think. Produced by Phil Spector.
song by Aaron Schroeder & Chuck Kaye. Today is not a day for throwing your raincoat in the river.
Sammy had a few more releases into the mid 60s, including one 1964 single on Motown. I can see no news of him for the past few decades, but it is to be hoped that he's still around and celebrating his 80th birthday today.
