I think it's well worth seeking out torrents of two of the programmes being broadcast.
Firstly, The Beatles At The Beeb has some great interview material and an interview with the fabs from the time they were filming Help! It's a new interview, at least on me.
Secondly, and best...The Record Producers: Sir George Martin. This has some fantastic material, not least a breakdown of the master of Come Together, including a guitar lick by George Harrison that didn't make the final mix. Also, there's a fantastic guide vocal by John Lennon.
Check them out!
