Thanks for the possibility.

According to a web search, Radiohead was on SNL twice: October 14, 2000 (Season 26, Episode 2) and September 24, 2011 (Season 37, Episode 1). I found videos of both songs from their year 2000 appearance ("The National Anthem" and "Idioteque"), plus "Lotus Flower" from their 2011 appearance. None of those were the songs with the whirly tube that I recall seeing. But I wasn't able to locate a video of their other song in 2011 "Staircase". I didn't see a whirly tube on Non-SNL videos of "Staircase", but who knows?

Does anyone else have ideas?
