Much more funny, up to date and culturally important than the clip below, this is the only surviving clip of the Beatles singing Ticket To Ride on Top of the Tops in 1965. The BBC wiped all the tapes of early TOTP during one of its many frugal but stupid moments. This fragment survived because it was shown during a broadcast of Dr Who as a glimpse of the distant past seen through some sort of device in the Tardis.
So it's a glimpse of the distant past showing up as a fictional glimpse of the distant past in a long gone TV show, on the show's internal TV. That's very meta. Deep.
Or just watch the first Doctor and his companions demonstrate how to groove to a Beat Combo in authentic fashion. But wait, they're actors, not real fans. They are faking their authenticity, despite being of the correct non-Austin Powers time period! That's deep too! I need a drink.
Can I just say that at least in the last two clips I've put on the blog, I haven't said anyone is hot? I think that's progress.
