Not the Beatles
More FMU blog stuff: Anthony Newly singing Within You Without You from a 1977 TV special. "I think the greatest reason for the classic quality of the Beatles' music is that they were constantly experimenting, striving for change. Each song brought new growth, new meaning." It's particularly funny if you keep in mind that Bowie has cited him as an influence. The ending of the TV show is also pretty surreal. I'm sure Percy Thrillington enjoyed it.
Also, check out Cook and Moore's excellent Beatles parody. They said it was supposed to be a Beach Boys parody, and it sounds more like Smile (in February of 67!) than anything, but their accents make it sound it more like the Beatles.
