I just got the Retrospective CD; it was a promo issued in 1993 for Jackson Browne to coincide with the release of "I'm Alive." (it was also remastered by Greg Calbi). Anyway, the version of "For A Dancer" on it is different than the familiar one I hear on "Late For The Sky." You hear a hi-hat on each beat during the start of the song, which you DON'T hear on "Late For The Sky"'s version, and furthermore Browne's voice is mixed down with some echo, like he's miked farther away. On "Late for The Sky"'s version, his voice is dry and his voice sounds like it's mike closely. I'm certain it's two different performances, too, because they're so different and because everything, including Browne's singing, is musically a bit different. Does anyone know what version I'm listening to on the "Retrospective" version? I don't think the song was ever released as a single, much less, had a single mix made for it.
