I'm hoping one can really like "Help" (which I do), but also think it probably not single material at the same time?
Well, if Herb had never given them "Close To You", and Richard hadn't seen the Crocker bank commercial, then the second album would have been quite different, and "Help!" would at least have been in the running for the next single.
That's a lot of "ifs", but then fifty years hence, all we have is what we have and "ifs".
