I'm writing a paper on OP Nayyar and was wondering if anyone know's why OP Nayyar never worked with Lata Mangeshkar? I asked my dad and he said that long ago OP Nayyar had comissioned Lata Mangeshkar for a song but she was either late or never came to the recording and he refused to ever work with her. Does anyone know of a source for this information, perhaps an article or website?

yes that's right salim
only i dont know the source f this information, or you can also look in the OP NAYYAR forum
some members added articles from OP NAYYAR.
