That’s a great boxset Steve, I have it as well. All the Springfield recordings, in better-than-original LP sound quality. 5 LP’s for a hundred bucks, cheaper than Mint copies of OG’s (I ditched mine after getting the box). Thank you Neil!
By the way, the first pressing of the debut album did not contain "For What It's Worth." That was added to later pressings after the single proved to be a radio hit.
