During the filming of Cameron Crowe's The Union - on the collaboration between Elton John and Leon Russell, Stevie Nicks dropped in to the Village studio where they were recording to meet Leon and to thank him...
I believe this was filmed during the time Stevie was in the studio laying down tracks for "In Your Dreams" in 2010. This film "The Union" made it's premiere in late 2011 and was televised on HBO in January, 2012.
Stevie tells Leon that after she and Lindsey Buckingham opened for him as part of the band Fritz in the early ’70s,
“That’s when the two of us thought,
‘That’s it. We’re gonna go to LA. We’re gonna do it.”
