The song was written by Roger Taylor, the drummer :)

I'm sure Lady Gaga would have become that big even without this name :)))

Actually,he didn't writhe that song.The drummer of 'Queen' did.I don't remember his name,but my sister told me that.

Well, Rob Fusion was her Manager, Every day, when Stef came to the studio, instead of saying hello, I would start singing "Radio Ga Ga". That was her entrance song. [Lady Gaga] was actually a glitch; I typed 'Radio Ga Ga' in a text and it did an autocorrect so somehow 'Radio' got changed to 'Lady'. She texted me back, "That's it." After that day, she was Lady Gaga. She’s like, "Don’t ever call me Stefani again."

Stefani¡

I just taught the other day imagine if there was no Radio Gaga,what would Gaga be called?!?!?
