On Sunday, 10 January 2010, he celebrated his 70th birthday (Sapthathi) at Kollur Sri Mookambika Temple with 'Sangeetharchana' (classical devotional songs), along with 70 singers before goddess Mookambika. The Sangeetharchana included "Pancharatna Gayana" of Thyagaraja's poems. He also took part in the Vidyarambha function. All India Radio broadcast the special Sangeetharchana all over Kerala. Yesudas also has many songs devoted to Lord Ayyappa including the hit song "Harivarasanam". In 2002, during Marad massacare, he visited the place along with the veteran poet Sugathakumari, and conducted classes against violence. Harivarasanam, a devotional song musical version composed by G. Devarajan, recited before closing the temple at Sabarimala was sung by Yesudas. Though there have been many different renditions of this song by many different renowned singers, Sabarimala officially uses Yesudas' voice for Harivarasanam every day.
