Songs by Joshua James

Hello folks,

I wonder if someone has the talent to figure out the chords to Joshua James' Sister, So Did I and Holly, Halej. I don't have that kind of hearing that I know how to figure out the chords but they do not seem incredibly complicated to sort out. So if someone has an idea on what the chords are on those three songs it would be much appreciate. They are not to be found on any other guitar tab or chord site.

Sincerely,

Professor Testudo
