In another thread, somebody asked if U2 planned a Tom Petty tribute, and one of the moderators mentioned they did one during their recent Mexico City show. After I looked it up, I posted a thank you note on the thread for the band. I don't know if Bono, The Edge, Adam, or Larry will ever see it, but I didn't want to waste an opportunity for gratitude (and now I should thank the moderator for telling us all about it. I feel bad I didn't think of that sooner.)
