Dennis performed with other "Quarantunes" for a special event for the Hollywood Bowl.
Here's the paragraph that featured the songs DDY performed:
Saturday proved to be yet another four-hour marathon concert. Beck performed "Everybody’s Got to Learn Sometime" from Eternal Sunshine of the Spotless Mind and a cover of Prince’s "Raspberry Beret"; Bryan Adams turned out "Cuts Like a Knife"; Elvis Costello contributed "Alison" and "(What's So Funny 'Bout) Peace, Love, and Understanding"; The Killers showed up in a sleek black-and-white video with "Caution" and a Tom Petty cover of "The Waiting"; Styx star Dennis DeYoung, a return guest in a USC sweatshirt, performed "Lady," "Come Sail Away" and "Babe"; Gloria Gaynor sang "I Will Survive"; Carlos Santana and wife Cindy performed "Black Magic Woman" and "Europa" from Hawaii; Rob Thomas followed them with a string of hits including his Santana collab “Smooth”; and Seal took time out of a house party to perform a never-heard-before original song followed by "Crazy" and "Kiss From a Rose."
