After Lindsey Buckingham's decision to leave Fleetwood Mac, Neil Finn was chosen to appear in the band's touring lineup.
Many people were surprised by the replacement but the decision to pick Neil was partly due to Mick Fleetwood and Neil Finn being close friends for years.
In 2016 Fleetwood called Finn a 'new music friend' and both of the musicians took part in the recent Concert for Our Lives.
Fleetwood also sat in with Finn on a cover of the Crowded House hit 'Don't Dream it's Over'.
Fleetwood mentioned he was a fan of Crowded House as far back as 1989, and the group later got Crowded House producer Mitchell Froom to oversee three of the four cuts on Fleetwood Mac's 2013 Extended Play EP.
Fleetwood travelled to New Zealand in 2016 for a studio collaboration.
"Fleetwood Mac has always been about an amazing collection of songs that are performed with a unique blend of talents,” Fleetwood told Variety. “We jammed with Mike and Neil and the chemistry really worked and let the band realize that this is the right combination to go forward with in Fleetwood Mac style. We know we have something new, yet it’s got the unmistakable Mac sound."
