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.

 I'm listening to Fastway which was named after Fast Eddie Clark from Motorhead and Pete Way from UFO.  However, Pete left before they started recording. 
The Who were The Detours before they became aware of another band using that name.
Not sure where the "Rush" posters got their info but Rush Hudson Limbaugh started his career in 1967.  The band "Rush" debuted in 1968.

Coincidence?  I think not!
@stevecham : The Who were called the High Numbers! I got this from my double LP "The Story Of The Who".
