Well lads! Experienced guitar player here, despite growing up in Ireland I never got involved in the trad scene. As I've gotten older and wiser, I've started to feel the call! As someone with no real background in trad, I was wondering if anyone could give some advice on getting started. Is it okay to just show up to a session and follow along? Or should I have a little repertoire in my back pocket before showing up? If so, are there any resources / playlists of tunes you can share?

Apologies if this has been asked a million times, I did a search and didn't find anything! If it's relevant, I'm based in Berlin now, I know there are a few regular sessions across the city.
