Vinyl find

So a friend of mine's dad got me into collecting records a couple years back. He listens to all the old stuff - Psychedelic, bluegrass, rock n' roll, folk etc. One day we were both at our local record shop when I found a copy of an album called "Bongos Over Balham" by Thrillin' Chilli Willi & the Red Hot Peppers, a pretty obscure 70's bluegrass band. My friends dad mentioned how good an album it was and that he'd never seen a copy besides the one he owned. I bought it and after going back to his house to listen to it, he pulled out a copy of their first album from his own collection, named Kings Of The Robot Rhythm. He said again that he'd never seen a copy besides his own. He also said a member of the band was a good friend of his back in the early 70's. After hearing the first album and loving it, I never thought I'd see a copy due to its apparent rarity. Fast forward a couple of months and I'm in a different record shop, still in the local area, and I (of course) find a copy of Chilli Willi's first album! Unfortunately the shop wanted £30 for it, which I didn't have at the time, so I sadly put it back in the rack and stuck with my cheaper options. A month or so later I went back to the same shop to see if they had any new stuff in, and whilst looking through the new stock box, I find the same copy of Kings Of The Robot Rhythm, marked down in price to £15. Of course I bought it straight away, and took it round to my friend's dad's place. We got the record out for a listen, and as I tipped the record out of the sleeve I felt another piece of paper fall into my hand behind the record. As far as we know there wasn't supposed to be a paper insert with the record. I unfolded it to find a page torn from a 1974 issue of Melody Maker magazine, complete with a full page spread focusing on Thrillin' Chilli Willi! Even stranger, one of the paragraphs described a disagreement the band had with their label over the release of their first album, and stated that Kings Of The Robot Rhythm was only released in the UK, on a limited run of 300 copies, before the label cut off production due to the dispute. Yet me and my friends dad had our own copies, as well as a friendship connection from the early 70's. Very spooky!
