How did a bands' name originate?


I heard that the name Rush originated from their producer's anxiety from the record label to name that band.

Pink Floyd got their name from two jazz musicians Roger (Syd) Barrett admired named Pink Anderson and Floyd Council.
Death Cab For Cutie got their name from the song performed by The Bonzo Dog Band in the Beatles' Magical Mystery Tour movie scene  in which John and George go to see the gig.
Rush was actually named after the euphoria Geddy and Alex got while playing their music as teens. 
Bad Company named themselves after they saw the Jeff Bridges western of the same name in 1972. BTW, the movie is still as good today as it was then.
