This one's a bit of a mystery. It's a Castle Film, meaning a commercial home movie release. It's a vast amount of musicians marching around and playing "76 Trombones" from Music Man, and at the end of the number, the gentleman you see conducting it all is Meredith Willson, who wrote that fine show. But what was this done for? The building they're marching around is CBS Television City at the corner of Fairfax and Beverly so I'm guessing it was done for some TV special in the early sixties…and that's all I know about it. Anyone else got any ideas?
