Is "Time Has Come Today" by the Chambers Brothers (1966) the first dub song? I mean, obviously not in the historical sense, but in the sense that people will call the Stooges (or the Sonics, or the MC5, etc etc) the first punk band. Here's a one-minute example. Is there any earlier hit single fooling around with dub-type studio effects like this? (Probably.) Examples solicited.
