Funnily enough, our drummer has right trouble with 3:4 time as well... We've got one song where the 2nd chorus ends with 8 bars of 3:4, the last 2 bars are a rest ready for a bass break which is in 4:4. He plays the 6 bars we play in as 18 bashes on the snare, which works quite well, but it took forever for him to get the rest bars; I said count "1-2-3, 2-2-3 for the rest" and he was adamant it was 7 he had to count to, which meant for the first few gigs he started a beat late! He's finally got it, but doesn't understand...
