I think Warning Signs was abandoned at the early demo stage because descarded by the movie producers, otherwise Bray would have mentioned a final produced version in the recent interview about his 80s unreleased tracks (he explicitly did it for Each Time). My personal opinion is that Warning Signs Bray demo may be featured in some film brolls or rehearsals & Gambler Bray mix is obviously in the final movie and they come from the same Bray early sessions, they sound too rough to be a final production by Ramone.
Basicly same situation of Into The Groove & Desperately Seeking Susan version.
Crazy for you, don't know, since it's a different story, not being a Bray track.
