Well, the Wurzels and The Yetties are both still around, and perform what is sometimes described loosely as "Scrumpy and Western" music, and has some similarity to what Shag did, being based on West Country humour (Shag's from Gloucestershire, Wurzels from Somerset and Yetties from Dorset).

Shag Connors was pretty unique though, and those other artists aren't quite the same. He was actually a fine singer if you look past the humour, and of course many of the songs he wrote were fairly 'serious' songs.

Adge Cutler (the founder of the Wurzels) was another one-off - some of his stuff is still available on CD, I believe. I've always been a fan of his, and preferred his material to the later Wurzels' stuff.
