Willie Nelson teamed up with some new friends at the Hollywood Bowl Sunday night, with both Neko Case and Ryan Adams opening for the American icon. Adams produced and plays, along with his backing band the Cardinals, on Nelson's upcoming 'Songbird' album, an 11-song collection featuring covers of songs from the likes of Adams (his 'Blue Hotel'), Gram Parsons and Fleetwood Mac.

Case seemed particularly thrilled by the honor, as she proclaimed at the end of a stunning 40-minute set, including a cover of Bob Dylan's 'Buckets of Rain.'

Adams, in his Hollywood Bowl debut, let his music do the talking, except for an amusing tangent about eggs. And while Nelson had new friends in the building, he didn't forget some old ones, honoring Merle Haggard with 'Working Man Blues' and performing 'Me & Bobby McGee,' which was written by his Highwaymen band mate Kris Kristofferson. Nelson also remembered a fallen Highwayman, dedicating 'A Good-Hearted Woman' to his late friend Waylon Jennings.
