At the recent Melbourne Ukulele Festival a couple of us did UK player Peter Moss’s “Ukulele Fun Shop” workshop and really enjoyed the experience.  He is a great teacher and everyone was soon doing his medley of Rock n’ Roll songs like old hands.  If you get a chance, make sure you attend one of his workshops as they are most helpful and great fun.  Below is a video of the same workshop that he did in the US in 2015.
