I tried to find if she sang any Rajasthani songs. I asked the well known record collector Girdharilal Vishwakarma from Rajasthan, he said none. Then I looked at the Encyclopedia of Rajasthani Films by the well known Rajasthani researcher M D Soni. He has listed sisters Asha and Usha but Lata is not listed in the book. There is also a comprehensive book, Lata Smagra, compilation of all songs by her, compiled by Suman Chourasiya, the well known record collector from Indore. The book does not mention Rajasthani. That's all I know.
