In recent years, the quality of Beatles scholarship has risen considerably, and the old days of accepting and repeating any old data (even coming from sources that should be credible) - without examining it deeper to see if it really stands up - are long gone.

Examining how their recordings were produced tells us a ton about how the group operated, and therefore getting it right is pretty important to understanding what we're hearing. My two guests - Marcus Phelan and Andrew Shakespeare - are 2nd-gen fans, hailing from Australia. Both are musicians who've been playing for decades and have been studying The Beatles' music for just about as long. We selected a group of songs that have been disputed as to who is playing what and how the recordings were constructed for this first installment of Contentious Credits.  Learn more about your ad choices.
