[1] He was best known for assembling tribute albums and events featuring a wide variety of artists and musical styles (jazz, classical, rock, Tin Pan Alley).

Following earlier stagings, in January 2010 Willner produced his pirate-themed concert event Rogue's Gallery for the Sydney Festival.

The multinational cast included Marianne Faithfull, Todd Rundgren, Tim Robbins, Richard Strange, Gavin Friday, Anohni, Peter Garrett, Baby Gramps, David Thomas, Sarah Blasko, Katy Steele, Peaches, Glenn Richards, Liam Finn, Camille O'Sullivan, Kami Thompson, and Marry Waterson.
