Who You Are lyric change

in The Porch
why were the lyrics, “circumstance, clapping hands”changed to “Avalanche, falling fast” on recent versions of the song. Avalanche even sounds awkwardly dubbed in.

Footsteps has the harmonica part layered on, Brother has the vocals stripped and a Mike part re-recorded for that release.
To the best of my knowledge the variants of Black Red Yellow, Hard to Imagine, Wash, Drifting, Dirty Frank are alternate takes.
"U" I've never given enough mind to in order to really know if that is a re-record or simply an alternate existing take.

I dont think anything was ever confirmed. They still do the original version live don't they? So that would make sense that it was an unintentional change or that they had no choice because it was damaged or lost.
