The original Tonights the Night is my holy grail. How did you come across it?
The original blotter paper covers are out there, it's just hard to find one w/ no ring wear, corner wear, etc. with a mint record. I got mine for $15 at Bullseye records in Milwaukee. It's one of those hard to find lps that isn't $100 yet.
Besides a picture inner sleeve of the band playing, some copies came with one of 3 different inserts (or none)...Here's a list of the three, including the Dutch insert translated into English http://hyperrust.org/General/TTNInsert.html
