I grew up around old time and bluegrass, where the extra beat was thrown in at seemingly random times, seemingly to all but the traditional players.
Now out here in mariachi country, and darned if the guitarron bass player, and the guitarist when thumping the guitar bass strings, don't throw in a little hiccup of a delay on the down beat.
Just some of the things about different music in our great land that continue to fascinate me.
