Don't think there's really a connection, except that Elliott Smith produced the album Featuring "Birds" that has this on it. Also, Sam who sings and plays guitar/keys for Quasi was Elliott's live bassist whenever he toured with a full band, and Janet was Elliott's drummer for the XO tour.
Coomes and Weiss worked with Smith, Coomes notably with Heatmiser, I believe Weiss was involved with the creation of Either/Or which was presumably around the time BOBN was written as it's an Either/Or B-side (I remember hearing that it almost brought her to tears, in a good way... something like that). The two albums were both released in 98 so your guess is as good as mine.
Jesus I love Quasi lyrics.
