No information whatsoever seems to be available of The Icemen themselves, who were Gino Armstrong and James Stokes. The indentity of the Icemen was confirmed by Jimmy Norman in a at present unpublished interview by Steve Roby, and it's also confirmed by the Icemen track "Only Time Will Tell" where the lyrics include the line "I wonder will she say "I love you Gino" everyday". This line is sung by the singer with the bit higher vocals which would suggest that it's Gino Armstrong and that James Stokes was the one with a deeper voice (if anybody can tell me the real musical terms for the vocal ranges I'd be happy to use those...).
The group seems to mainly have been a vehicle for songwriters / producers Robert and Richard Poindexter. The Poindexters did release records themselves as "the Poindexter Brothers", but it seems that the"solo" recording career of Richard and Robert Poindexter didn't really take off, so they moved into working behind the scenes, writing songs and putting together groups to perform them.
Richard & Robert Poindexter are nowadays probably best known for co-writing the song "Thin Line Between Love & Hate" first released by The Persuaders on the single ATCO 6822, composed by Richard Poindexter/Robert Poindexter/Jackie Members and produced by "The Poindexter Bros", arranged by Richard Poindexter and strings arranged by Arif Mardin. The 45 was released in August 1971 and made number 1 in the "R&B" and number 15 in the "Hot 100" Billboard charts. Subsequently it has been covered by several other artists.
The Persuaders also released another hit single composed by the Poindexter's, "Love Gonna Pack up (And Walk Out)" (Win or Lose 220) (Richard Poindexter/Robert Poindexter/Jackie Members/Ray Lewis), number 8 on the "R&B" chart and 64 on the "Hot 100".
Both tracks were also included on the Persuaders lp "Thin Line Between Love & Hate" (Win Or Lose Records SD 33-387) released in 1972. The catalog number is a Atco one, "Win Or Lose" was a label owned by the Poindexter brothers distributed by Atlantic.

ABC RECORDS 45-11038 - 1968? Produced By George Kerr
The tracks on this release were arranged by Richard Tee. He was a much in-demand session player & arranger in the sixties in New York City, later working together with a impressive list of famous musicians including Cornell Dupree (of King Curtis & the Kingpins). Another Hendrix connection could be the label "BRAN-T" that released the Billy LaMont 45 "So called friend", this recording was produced by Johnny Brantley, the label name could be a combination of their last names, "Brantley-Tee" > "BRAN-T", but so far this is only speculation on my part.
