Buffalo Springfield. "Baby Don't Scold Me." In stereo, as nature intended.
This was on the original pressing of the Springfield's 1966 debut LP; when "For What It's Worth" went Top 10, ATCO hurriedly re-pressed the album with the hit in its place. The mp3 is from a vinyl transfer; the stereo mix, alas, has never been on CD (the version that finally surfaced on the Springfield box set a few years ago is the mono). I think the stereo is a lot more vivid, but on the other hand, having it in two-channel means you can really hear how sloppy the production is.
I'd loved the song (one of Stephen Stills' best, and kind of proto-power pop, I think) since forever, and I actually tried to interest the guys in working it up fairly early on. Unfortunately, the only copy I had of it was a wobbly old cassette a friend had taped for me in the early 70s, the woeful sound quality of which may have been why I was ultimately unsuccessful in pitching the tune. In any case, we wound up covering "Go and Say Goodbye" instead, which was okay by me, obviously.
