Edward Van Halen has a big finger stretch on Ice Cream Man. I've been working on stretching like this since I was young on guitar (have you ever seen Alan Holdsworth play?), so when Guitar Tricks asked me to do Ice Cream Man I was all in.

No arthritis, just warm up slowly and try smaller stretching distances first, before attempting Ice Cream Man solo.

I can help you with this in my live '1 on 1' lessons here on Guitar Tricks:

Hope this helps.
