Quoted from zr11990:
Go to YouTube and listen to he song from the concert in Central Park video. I swear is says better not worse.
From el Wiki:
The lyrics to this song on There Goes Rhymin' Simon differed in wording from those on the The Concert in Central Park (1982) and Paul Simon's Concert in the Park, August 15, 1991 albums. The former (the album) said, "...everything looks worse in black and white," but the latter (the concerts) said, "...everything looks better in black and white." While it might be easy to read into the change in lyrics, Simon said, "I can't remember which way I originally wrote it -- 'better' or 'worse' -- but I always change it....'Kodachrome' was a song that was originally called 'Goin' Home.'"
