Thanx PhilMH 4 your input. You're absolutely right. And I always trust the crew of serious record collectors at Both Sides Now and their discographies, so I 100% agree that this should be changed 2 1966!!
This might be a 1972 pressing, but Both Sides Now's Exodus label page suggests that this catalogue number was first issued in 1966; the Chicago address on the back cover would tend to support that, as the later re-incarnation of Vee-Jay as VJ International was based in Hollywood, so either the latter company still had a lot of unused album covers left over, or they didn't bother to update the address for later printings.
