As we keep banging on about, Lindsey Buckingham and Christine McVie have teamed up to release a duets album, and we love it.

As part of their promotional slog, the pair appeared on The Tonight Show with Jimmy Fallon, The Roots, a bunch of kids, and a handful of toy instruments to unleash a version of their optimistic, excellent single ‘Don’t Stop’.

The kiddies are from the SeriousFun Children’s Network, a charity founded by late actor Paul Newman to help children with serious illness have serious fun. Fallon is a long-time supporter of the charity, raising over a million dollars for them a few years.

Check out the serious fun, below.
