Sum 41's Deryck Whibley Accuses Former Manager of Sexual Abuse in New Memoir

In his memoir 'Walking Disaster,' Whibley alleges that Greig Nori groomed and abused him during the band's early years.

Deryck Whibley claims that Greig Nori, Sum 41's former manager, groomed and pressured him into a sexual relationship starting when Whibley was 18.
Whibley describes a power imbalance, alleging that Nori manipulated and isolated him from others, including his bandmates and family.
Whibley alleges that the abuse continued for about four years, ending when a mutual friend identified the relationship as abusive.
Greig Nori has denied the allegations, calling them false and has retained a defamation lawyer.
The memoir's release coincides with Sum 41's farewell tour, as the band prepares to disband after nearly three decades.
