Harry reportedly hung out backstage and even made a cake for Stevie Nicks! He had teased the concert earlier in the day, when he posted a throwback pic of Stevie, captioning it "SN."
Their mom was there in spirit, with Gemma tweeting: "FaceTime-ing my beautiful mother @MrsAnneTwist from @fleetwoodmac I'm feeling so much love Miss you mama"
Meanwhile, Mick Fleetwood recently told Q magazine (via Contact Music) that he and Harry are pals after Mick took his daughters to a One Direction show and met backstage. He explained, "One-by-one (Harry and his bandmates) all came in and said, 'Oh my God, we've just plagiarised three Fleetwood Mac songs in the past week!' They said to my girls, 'We got so far into some of your dad's drumming parts that we thought, 'Oh, we can't do that, we won't be able to get away with that'... (Harry) writes to me from weird places, and has met Stevie (Nicks). So, yeah, a funny little relationship."
