A lot of b-sides could have been great singles - summer rain, spanish eyes, flower child (not really a b-side), are you gonna wait forever... usually they just need a bit of work. The lyrics on Always are one-half wonderful (put your head over the parapet, be uncool, yes be awkward) and one-half embarassing (always wear a safety vest...). But I think songs like always that tended to morph into other songs (always>>beautiful day) never get finished, and for good reason.
