We see Sathya Sai Baba almost continually during bhajans, mainly at Sivaratri, during the 1990s. The first 10 bhajans are led by Him:

Prema Mudita Manasa Kaho (minute 2:50),
Sathyam Jnanam Anantham Bramha (6:55),
Govinda Krishna Jai Gopala (10:50),
Rama Kodanda Rama (14:32),
Bhajana Bina Sukha Santhi Nahi (19:05),
He Siva Sankar (22:14),
Love is My Form (24:45),
Siva Siva Siva Siva Yanaradha (26:05),
Subramanyam (28:40).

The next dozen or so bhajans are led by others, as Sai Baba walks around or sits in His chair, listening.
