I know most of the guys mentioned are American,but we do have the odd compeyent musician here in trhe U K . I would like to bring to your attention one Simon Mayer,who I rate as World No 1. Simon plays Folk,,country,Western Swing, Classical and even the odd bit of Jazz.
Check out any thing by Spredthik,The Mellow Virginians,or the Mandolinquents,as well as all sorts of solo stuff in his own name.
