Paul McCartney and Ringo Starr take part in a public webcast today (3 April).
The last-surviving Beatles will endorse the David Lynch Foundation's initiative to teach a million at-risk youth to meditate.
Both Beatles have been involved in transcendental meditation for years, and will be joined by Lynch and hip-hop impresario Russell Simmons at the conference.
You can watch from 12 noon EST (5pm UK time) at DavidLynchFoundation.org.
McCartney will later be joined by Eddie Vedder, Moby, Sheryl Crow, Ben Harper, My Morning Jacket's Jim James and more for a benefit concert at New York's Radio City. Proceeds from the event will go toward the David Lynch meditation initiative to teach meditation in schools.
