Oh there’s plenty to choose from in Meic’s repertoire! (another talented South Walian 
) as for hints - where do I start! My favourites include Cân Walter, Merch y Ffatri Wal, Brawd Houdini, Môr o Gariad, Shwmae Shwmae, Dim ond Cysgodion, Crymych Trip, Rue San Michel, Strydoedd Aberstalwm… best not hijack this thread too much though!
For great songs in a North Wales accent, check out Gai Toms/Mim Twm Llai - you can’t go far wrong with Gai’s stuff either (and he’s done some cracking Meic Stevens covers too!), and also in N Wales accent, of course I have to mention the band I used to play for, Bob Delyn a’r Ebillion!
