Who knows what gems exist in the master tapes of your favorite albums. Open Culture is hosting a video of legendary Beatles producer George Martin at the mixing board with his son Giles and George Harrison’s son Dhani.What are they doing? Oh, just digging through the tracks of Abbey Road. From OC:

Together, they play with the mix of “Here Comes the Sun,” and then the wondrous little moment of discovery happens. They stumble upon the long lost guitar solo that never made the final cut.

The iconic final version of the song is just fine minus the solo, but this is a great glimpse into Harrison’s and The Beatles’ creative process.

Look and listen right here.

Thanks to Mason Fann for the tip.
