"Glad and Sorry" is a bittersweet Ronnie Lane song from the last Faces album, Ooh La La. It's one of those songs that works better when you don't try to analyze it. It's all about the performance. You pick up the vibe from the music, and maybe a few words resonate, but that's all you need to know.
Twenty-something years later, alt-rock supergroup Golden Smog covered it on their first full-lengther, Down By the Old Mainstream. The main piano riff is rendered on electric guitars, giving the song a bit more edge, but otherwise their version is spot on. The loose, relaxed vibe that permeates the album made "Glad and Sorry" a perfect fit.
