Toronto radio station 104.5 CHUM FM announced Monday that radio personality Darren B. Lamb will join Roger and Marilyn every weekday morning.

Lamb joins the popular morning show after a five-year run as 104.5 CHUM FM's afternoon drive home host.

"Darren is a fantastic addition to Roger and Marilyn," said David Corey, program director for 104.5 CHUM FM.

"His sense of humour, love of music, and unique perspective on pop culture makes him a perfect fit with Roger and Marilyn."

Lamb's afternoon drive home show has been the top-rated drive home program in the Greater Toronto Area over the past five years. Before joining CHUM FM, Darren worked at several radio stations in Vancouver, including Z95.3 (now know as Crave 95.3) where he hosted its popular morning show.

CHUM Radio is a division of CTVglobemedia, which owns CTV and The Globe and Mail.
