) sent me a list with all that Jeff has been recording throughout the years.
I don't think I've seen such an extended list before.The only things missing are the solo releases,which are well known by now.
Thought I'd post this here for all of you interested to have a (complete,I guess) idea of what he's been doing for 30 years+.
Impressive,to say the least...
If there is something not listed,the only one who can add to this is JSS himself...if he still remembers! Busy bee!
