You know, I went down there when they were doing “Landslide” and I stayed there for six hours and watched them film the whole thing. I watched Gwyneth (Paltrow) and Brittany (Heather Morris) and Santana (Naya Rivera) sing the song 50 times, and I had such a good time. What I was very touched by was that Lea Michele, who plays Rachel, said to me, “You know, in all the big songs that we’ve done, which is many, nobody’s ever called us or come down or even written a note thanking us for doing ‘Jessie’s Girl’ or a Journey song.” They do such great versions of all these songs; the original writers cannot fault them. They’re magnificent – every one of them. And she goes, “Nobody except you has ever come down and told us that they thought we were doing a good job.” And I thought that was so sad. Very, very disrespectful.
