Hey fellow bodhranii:
Check out the current episode of Siar an Bothar at TG4.tv Click on "ceol" and scroll down the program list. This particular program opens with some comments by Nicolas O'Carolan about how the bodhran became popular in the 70's , and some great film of the man who invented the new rhythms, Johnny "Ringo" McDonagh. He demonstrates the motor rhythm for a minute or so and goes into a couple of nice reels with Frankie Gavin on whistle. It's 'as gaeilge', of course, but with subtitles, Buiochas le Dia!
