Looking closely at the record label; 1963 date if recording I think... I remember hearing play on AM radios, 4 track tapes, juke boxes, and HS dances maybe. OK, who remembers "wonder bar" radios in GMs? How about reverb speakers? what's that all about...
I have somewhere a Buick reverb unit that came out of a '72 GS455. It worked...sounded groovy man! But not really, sounded echoey. I think you had to be high to get the full effect. lol
Hang on to that reverb; it may come back in style along with crewcuts and bow ties ........ BTW, If my memory serves me after half century, reverb is better with certain types of music (IMHO) .
