I know that Renee and Jeremy aren't the first family musicians to do the "music lessons via YouTube" thing (hi, Cathy Fink & Marcy Marxer!), but their instruction on the oh-so-sweet "Night Mantra" is short and to the point. (Need lyrics or to hear the tune? Go here.)
Wonder if that translates to the ukulele?
