Here are two guys in their 60s staying faithful to something they learned in the 60s, besides rock and roll. Paul McCartney and Ringo Starr performed together for the first time since the memorial Concert for George, along with Donovan, Mike Love of the Beach Boys and younger, lesser stars, in a benefit concert for the David Lynch Foundation called "Change Begins Within." The purpose was to support teaching Transcendental Meditation in schools. The Beatles of course made TM famous by going to India (with Donovan and Mike Love) to learn it from the Maharshi (who died just recently) in 1967. The idea is not really so far out--a school in Oakland, CA taught mindfulness meditation to students and showed great results in conflict resolution, attentiveness, study habits and peace of mind. Various kinds of meditation have proven to help in pain management and stress reduction, since those crazy days of wild ideas in the 60s. Yeah, yeah, yeah.
