Swamy
Like K J Yesudas singing lot of Hindu devotional songs (Song Swagatham Krishna Saranagatham Krishna is his special and melts our hearts) and being a renowned Carnatic singer, there is one Dr D A Joseph who gives discourses on Vaishnavism, Ramayanam etc.
He is given Perumal Mariadhai in our temples.
If earlier known, kindly excuse me.
Yours sincerely
Swami, D A joseph had born in a roman catholic christian family.But, he got attracted towards hinduism and vaishnavam .He also got panchasamskaram and learnt many scriptures like mumukshupadi,kamba ramayanam,prabandham etc..,Now he leads his life as a upanyasakar.He did many prachars to spread vaishnavam.He usually gives upanyasams at temples.At temples,as a upanyasakar he was given mariyadhai.
Adiyen.
