Pink has at least one fan of her cover of Jefferson Airplane's "White Rabbit," which appears in the Disney film Alice Through the Looking Glass, the band's own Grace Slick.

"It's good. Pink has the vocal power, which is all I care about," Slick told the Wall Street Journal.

"Over the years, I've heard a lot of versions of the song where singers don't have the attitude or vocal force you need on it. Pink knows how to sing."

Slick described Pink's vocal talents, calling her approach to the cover a "straight attack" of the song.

"Pink sings with power, but it's something more. You sense that if she wanted to, she could open the throttle even more at any time.

That coiled energy creates drama and catches the ear."

Slick also revealed that she won't be seeing the film for some time, due to a foot condition.
