asking for a rise? (Pink Floyd)

Hi everyone, it just occurred to me that in the song ‘Money’ by Pink Floyd they say ‘But if you ask for a rise it’s not surprise that they’re giving none away’. Now, ‘rise’ clearly refersto a pay raise. My question is why do they use ‘rise’ instead of ‘raise’? Is it so it rhymes with ‘surprise’?

Many thanks,

“(pay) rise” is BrE; “(pay) raise” is AmE.

That’s very interesting, I didn’t know that![YSaerTTEW443543]
