Yeah, he should try to convince those of us who know a little bit of/ speculate about the origins of music. Didn't MUSIC itself actually start with drums/ percussion? What's probably the oldest instrument ever invented? Probably some ancient/ crude percussion instrument. Why? Because maybe some caveman started banging on a hollow tree trunk, and "eureka", he found the banging pleasurable enough to keep on doing it. And then the caveman showed this discovery to fellow tribesmen. And thus the first musical band emerged.
Sounds about right to me (maybe a stretch, but sounds reasonable). It could have also be the wind instruments (someone hearing a sea shell's sounds in blowing winds, or something like that), but it sounds less probable and more serendipity.
