My facebook friend Mukund Marulkar is a huge fan of Shankar-Jaikishan and is always posting interesting stuff about them. Recently I saw a photo by him where it was declared that SJ were going to be the music directors of the above film. I am not sure what happened, in the end they were not at all mentioned in the credits.
Here is the photo, thanks to Mukund Marulkar and, screen caps from the DVD of the film. We can see the Indian cast members and crew, Interesting to see Ellis R Dungan mentioned. The music is by Ken Jones.
Now You Know!
