Fleetwood Mac singer Stevie Nicks believes that every band should have a mix of men and women because it “casts a romantic spell”.

In an interview with Mojo magazine the Go Your Own Way singer said: “I think every band should have a girl in it, because it’s always going to make for cooler stuff going on than if it’s just a bunch of guys.”

She added that the mixed gender dynamic “casts a romantic spell,” despite whether any of the members of the group are together or not.

Fleetwood Mac has returned to the UK this week as part of their European tour, playing with keyboardist Christine McVie for the first time in 16, to rave reviews.

On Wednesday night British singer and songwriter Adele met Nicks before the show, and posted a picture of the pair together on Twitter, with the message: “So tonight was THE best night of my life. I love you Stevie Nicks!! The queen of melodies! Thanks for everything x”.

Nicks reportedly told the crowd that night about meeting Adele, and claimed the 27-year-old singer will be just like her when she’s older.

“I told [Adele], ‘You’re going to be me in 40 years’,” she said into the microphone. “You’re going to still be up onstage doing what you’re doing because of your song writing.”
