I've also noticed it
"Jah Wrote Me A Letter From Zion" is one of my all time favorite reggae songs. It sounds extremely fast and extremely slow at the same time. To me it's kinda magic, really. I was feeling so happy when it was re-issued on Rootikal 7" a couple of years ago. The same label that also put out "Leave The Badness Alone" by Singie Singe. Two killer 7"s.
The cd release sounds like a very nice vinyl rip to me. I believe the original master tapes of the "Weekend Lover" album are either lost or unavailable for whatever reason. A great re-issue - what else can I cay?
