Akashganga, released in 1959, is Hridaynath's first Marathi movie as composer.
On its VCD, I found a funny little Hindi song 'hame bhi bata' sung by Prem Dhavan. I say Prem Dhavan because that is the only male name listed under singers in the credits.
Interestingly, the credits show Pyarelal Sharma (of L-P fame) as Hridaynath's assistant on this film!

There are 6 more songs in the film (5 Lata solos and a Lata-Usha duet). I think they are easily available, but if anyone is interested, I'll be happy to upload.
