I've been going to folk festivals since I was in the womb Laura and I know exactly where you're coming from!
I'm 22 now, but I am sort of in the process of starting to get some material together with a friend who is 15 (she's in the finals of the young tradition awards in Derby on Saturday incidently!), so don't write us 20-odds off just yet, we're always eager to meet up with someone with talent in our own age bracket!
I couldn't have caught you at Towersy, as I was at Bridgenorth at the time, but I'm reliably informed it was a good festival!
