Does anyone know what chords phil is playing during the ascending line off the bridge? its right at 4:20 in the clip attached from 6/18/74. Any insight would be greatly appreciated!

Here is the archive post with the song

Phil is playing fifths within the chord of B which runs through for 3 measures during the "Shine" the solo starts over the verse chords, E Emaj7, etc.

I'm hearing Phil start the first of the 3 B measures with a B/F# chord, then up to a D#/F# chord, then F#/B (D# E F# line up), then B/F# again, etc. Classic Phil bombs.
