so far we have 6 different live recordings of IDWTBAB.
the only differences are
the first recording she says "Got a new philosophy" instead of "Got a fresh philosophy"
a few times she switches the word "golden" for "diamond" in the line "Don't need no golden ring"
a few times she says the word "love" after the line "Can we keep the ever after"
and of course a couple of the recordings don't feature backing vocals by Ari.
the first recording she sort of clapped along for the beginning of the song.
as time went by the kind of changed the way they sing the backing vocal part. example: in one of the recordings she adds an extra "you and me".
not very big differences.
What are the six? I think I only have four.
