I've never understood why a 60s Radio Station isn't available on the radio dial... A station that focused on the likes of 'Rain' and delved into the *back catalogues of all the other 60s groups I'm sure would find a healthy audience.
Oh, man, I hear ya! It's always the same ol', same ol'. There are literally thousands of fantastic tracks that never
receive any airtime and it's a shame.
Your comment in general, and this thread focusing on Rain in particular bring to mind a moment from my college days waaaay back in the mid-'80s. The local "live" college radio station was soliciting on air for requests. On this particular day it was raining cats & dogs so I called in and requested they play Rain. I even told them on which LP to find it (Hey Jude). The DJ said it would be the perfect song for the day and thanked me for my request. I listened to that darn show for about three hours afterward and they never played it. My only presumption is the station did not own a copy of Hey Jude.
