Brad isn't claiming that the Remington ammo boxes have anything to do with famous people or places. Big difference between that and what Fender's doing.
Also, as commenters pointed out, the seats in Hollywood Bowl were replaced in 1958 and again in 1981. Pardon me for doubting that these boards came from the original seats. I wouldn't believe it without provenance.
Hey, I still have enough walnut I bought in 1981 to build a guitar. It came from a tree chopped down by Dan'l Boone himself! (or maybe by Ed Ames with a tomahawk). It's true because I said so!
