SALUTING PRINCE

Behind-the-scenes clips from Let’s Go Crazy: The Grammy Salute to Prince are making their way onto the internet, beginning with Dave Grohl and Earth, Wind & Fire.

Grohl talks about jamming with Prince during his 21-night residency at The Forum in Los Angeles in 2011. EWF talked about their selection of "Adore," a deep cut from the 1987 Sign "O" The Times.

CBS will air the special 4/21, the four-year anniversary of Prince's death.
