A great a-side. It was on the 'In Our Image' album circa 1965, maybe their best all around '60s LP.
Any U.S. single edition of it is going to be rare too I think although I used to scoop them up cheap in mint because most people didn't seem to want them back in the '80s. Not sure if the promo of that is any rarer than any other Warners of the time.
There was a show on CBC-TV hosted by Terry and Susan Jacks where they interview Don & Phil, but then the Poppy Family play a lot of those great mid-60s Everlys songs that tended to go unnoticed in N. America. I guess CBC couldn't afford them to actually perform. You could tell what a huge fan Terry Jacks was/is. I think Clear Light hipped me to that particular Vancouver Let's Go show. If anyone makes a new doc on the Evs they could get some nice period interview clips of them there.
