that period simply weren't competent enough to master that, and instead went to the "one-two-THREE-four" that backed up rock from that point until much later. Contemporary pop music uses a "funk" dance rhythm that is lifted from Black artists, most notably James Brown...which, if carefully analyzed, turns out to be based on the old tango rhythm.
Anybody out there in Radio-Land make any sense of this?
