To be frank, I don't know what he's talking about. Isn't "Stumbleine" in the same condition as Rotten Apples? I can't tell the difference between the demo and the album version, and honestly, I'd say Rotten Apples is a stronger song than Stumbleine anyway. I'm not going to whine about song selection though (or at least not until I get to Set The Ray To Jerry).
Billy also says he's a fan of the lyrics, which is good, because they are pretty killer. They seem like they straddle the line between pleasant and drippy poetry on paper, but the delivery plants a firm foot on the 'affecting' side. It's a sad song, but it also has a very defiant side. After all, the song is a plea to "Love her when your love goes unrequited."
Funny side note: when introducing this song on the Zeitgeist tour, Billy said that he'd never played it before, apparently forgetting that he'd done so in 1998. Ouch.
