Shri Krishna Govinda Hare Murari
He Nath Narayan Vasudeva
I read somewhere that Bhagavan Das was so high and so famouse with the rock stars after the book be here now, he was pulled to the rock world with drug and Jimmy Hendrix.
He left the spiritual world and recently came back to start the kirtan.
Other famous Kirtan singer from Neem Karoli Baba is Krishna Das.
And Ram Das has been an always an inspiration to all of us.
I believe it is hard to go down and come up again spiritually than going up higher slowly with the devotion and Bhakti.
But this link is interesting.
