My son and I love watching Yo Gabba Gabba! on teevee. Our favorite episode is Sleep because it features two particularly delightful songs. The first is a lovely tune called Bedtime Lullaby by Mark Kozelek of Red House Painters and Sun Kil Moon. The animation is by Lippy. In the same episode is a fun performance of "Pajama Party" by teenage indie pop duo Smoosh. Viacom seems to have insisted YouTube yank the Pajama Party video, but Bedtime Lullaby is still available.
