Justin Timberlake literally got on bended knee before legendary singer-songwriter Bill Withers and credited his stone-cold classic "Lovely Day" with inspiring his smash hit "Can't Stop the Feeling." "It's very serendipitous that this man is sitting with us here today," said an effusive Timberlake.

It was one of many unscripted moments at a revealing and rollicking panel discussion and screening of Trolls for which Timberlake was film's executive producer of music. The evening was presented by the Songwriters Hall of Fame West Coast Committee for an audience of SHOF and Academy of Motion Pictures Arts & Sciences members at the 20th Century Fox Studios in West Los Angeles where it was also revealed that Timberlake would perform "Can't Stop the Feeling" at next week's Oscar ceremony.

The dynamic panel also included a rare appearance by superstar producer Max Martin, a nominee for this year's Songwriters Hall of Fame, and his fellow producer Shellback (Karl Johan Schuster) who together with Timberlake created the music for Trolls.
