You probably know the details better than I do (and perhaps there's a later twist I'm unaware of) but in 2022 Cocker denied that it was Stratou:

Speaking on BBC Radio 4’s This Cultural Life (via The Mirror), Cocker addressed claims that the inspiration was Danae Stratou, a Greek woman who attended St Martin’s at the same time as Jarvis, but confirmed that “it wasn’t her because she had blonde hair and the girl had dark hair.”
