Not the Walls or the Windows. Not even the Front Gates. It's like they picked the blandest, worst-sounding noun they could think of and just pluralized it. For the off-the-wall psychedelic sound Jim Morrison and co. ended up cultivating, they sure were stuck with the most boring and pointless of names.
Syd Barrett took the first names of two of his favorite blues musicians to create the moniker for one of the greatest rock bands in all of history. While it must have taken a long time for people to get used to saying they were really into something called Pink Floyd, I'm more concerned with what these guys might have been called had Barrett not gone with his mashup. Prior to the Floyd days, this group went by The Meggadeaths, The Screaming Abdabs, Leonard's Lodgers, and The Tea Set. In fact, it was only because another band called The Tea Set was set to play with them that they changed their name to the Pink Floyd we know and love. The Tea Set that usurped the title from them went on to die in obscurity--which is probably a good thing given how badly that name would have aged by now.
What confuses me here is that Bono and company came up with this one long before computers and text messages were really a thing. Did they somehow figure that "You, Too" looked too weird to be a band name, but its shorthand homonyms scrunched together looked pretty much okay?
"Hey. Hey, Lars."
"We gotta name our band, dude."
"Crap. You're right. We haven't done that yet."
"What are we gonna call it?"
"I dunno. We play metal, right?"
"What about...Metallic? That's a word with the word 'metal' in it. It's like we don't have to tell people what kind of music we play because it's already in the name. Genius."
"I dunno, dude, I don't think it sounds enough like a band. I think we'd better throw an extraneous vowel on the end there. Just so people know we're a band."
"Whoa. Dude. Yes. That's so metal. The metal-est."
