What finally prompted me to post was the kicker at the end of the radio broadcast: He's going to use musical forensics now to try something way more ambitious:
Brown isn't done with his musical sleuthing, either. Devlin says that Brown is now using Fourier-based analysis to determine who wrote certain Beatles songs whose true authorship is in dispute, such as "In My Life."The kind of core acoustic analysis in the Hard Day's Night case seems relatively straightforward, but you gotta wonder whether it's possible to tease apart composing styles between two guys who were working together so closely for so many years. At any rate, it's cool.
