I have stumbled across a fabulous site, made even more fabulous if you remove thoughts such as "how creepily paedophilic does this guy seem" from your mind. So yes here it is in all its glory:
www.violinmasterclass.com I suggest you check out the performance section, especially Monti's Czardas, one of my all time favourites, as well as the Scherzo Tarantelle - if I can ever play that I'll be a happy bunny.
