Where does the phrase 'my friends electric' come from?

Question:

Where does the phrase 'my friends electric' come from?

Is it simply paraphrasing the Gary Numan song 'Are Friends Electric'? Or is it from Philip K Dicks book 'Do Androids Dream of Electric Sheep' (on which the Numan song is based..and I haven't read :D ). Or something else...

I am not sure but most likely from Gary Numan
