What early 70's rock bands had violins?

Another band that featured the violin prominently was Caravan out of England. Their albums" In the Land of Grey and Pink" and" For Girls who Go Plumb in the Night" are very good. Two band members then broke off and formed Hatfeild and North another band which featured the violin .

Jean Luc Ponte...album called,Enigmatic Ocean...all instrumental...has electric violin,violatron...album has nice flow to it

Gatemouth Brown was a blues guitarist who also played the fiddle.  Not quite a rock guy, and his heyday was in the 1950s, but he was around the rock scene in 70s, too.

I think Roxy Music's Eddie Jobson turned up here and there for other bands, too.

Most of the 70's rock bands with violin players have been mentioned with one exception- the Dixie Dregs.
