So, sit back and enjoy the Magic of Helen :)
Alavudinum Arbhutha Vilakkum (1979) (Allauddin And Wonderful Lamp) is another Tamil film that Helen dances in that not too many have ever seen. It also stars Rajnikanth and Kamal Hassan.
Lastly, here's another rare Helen video from 1958's classic Tamil film Uthama Puthiranan. I supplied the raw video to Tom Daniel. He restored it and it now looks and sounds great. The song is called Yaradi Nee Mohini and Helen doesn't appear until 3:12. But it's well worth the wait as she dances marvelously, especially in the boogie-woogie finale. Enjoy!
