It seems that Robin is very busy doing tutorials at the moment. Here he shows his approach to the well known song Wild Mountain Thyme. The crosspicking pattern he shows can be used to accompany lots of more songs in 3/4 time. Even Daoiri Farrell uses it a lot, e.g. in his song Creggan White Hare.
This is part 1 of the tutorial. If you want to go further you can get it here.
