It seems George’s Strat of choice for the sessions was very likely the Bangladesh Strat before it was sanded to it’s natural finish.
Let’s take a look at the info we have.
- The Bangladesh Concert took place in August of 1971, recording on Lennon’s ‘Imagine’ (on which ‘How do You Sleep’ appears) finished by early July of the same year. Consistent with George having time to strip the finish between the two.
- The sonic blue Strat in the video has a maple neck, and a mint green 3 ply pickguard, an uncommon combination indicating it comes from the crossover period between Fenders white single ply, maple neck combination and the rosewood boards which were to become standard later. The Bangladesh Strat shares these features.
- The Strat isn’t set up for slide at the CFB as this one is here, but it would be when George taped his Dick Cavett Show performance on Nov 23 with the sanded Bangladesh Strat, so George was known to use it for slide, and seems to have favoured the instrument during this period.
- The spacing of the 12th fret markers on the fretboard is consistent between both.
- This Strat has the same strap as the Bangladesh Strat.
So, if my suspicions are accurate. Not only have we identified that the CFB Strat was originally sonic blue, we’ve determined that the finish was stripped between George’s recording sessions for ‘Imagine’ (probably ending early July) and the final CFB rehearsal on July 31!
