Does anyone know how to play the Travis or Travis Roll finger-picking pattern/style? I have the guitar tab for it, but struggling to play it. Would appreciate if anyone could show me how to play it properly etc.

Merle Travis? Lots of hints about it here. Guitar Land (http://www.guitarland.com/Travis.html)

Not studied him yet but i've heard his name a lot. Doc Watson is another great guitar player to look out for. Massively ignored compared to the likes of Chet Atkins.
