Elliot- best known for her work with The Mamas and the Papas - passed away due to heart failure in London at just 32 in 1974.

Michelle was the first presenter to speak at the ceremony, wearing black glasses, a black long-sleeved shirt, black earrings, black pants and black shoes.

'On our first meeting, Cass and I experienced our first acid trip. It was 1965,' Michelle said at the ceremony.

'We never came down. We bonded. She was my best friend. She gave me courage to sing when I thought I couldn't make a note. She'd say, 'Hey just go for it. You know I'm gonna make it.' And so I went for it,' she added.

Mama Cass was honored by singers Carnie Wilson, Chynna Phillips, Bijou Phillips and Mackenzie Phillips, along with Cass' child Owen Elliot-Kugell, Mickey Dolenz and more.

The group is know for their hits California Dreamin', Dedicated to the One I Love, and Glad to Be Unhappy.
