Paul McCartney and Ringo Starr are still meditative about their trip to India.
The two remaining Beatles were to share the stage Saturday night when McCartney headlined Radio City Music Hall.
McCartney said at a press conference Friday that the Maharishi had given the band a "great gift." He said it came at a time "when we were looking for something to kind of stabilize us toward the end of the crazy 1960s."
Saturday's concert, called "Change Begins Within," was to benefit director David Lynch's foundation. The organization's initiative is to teach 1 million at-risk youths how to meditate.
Besides Starr, McCartney was to be joined by Sheryl Crow, Donovan, Eddie Vedder, Ben Harper, Moby, Paul Horn, Bettye LaVette and some surprise guests.
