London was a premiere local for punk in the 70’s with the likes of the Demics and the Sinners. The Sinners were formed in the late 1970’s. They would play weeklong gigs at the Cedar Lounge and packed the house nightly with their pogoing fans. The Sinners also toured the gig route of southwestern Ontario and played Larry’s Hideaway among other Toronto Clubs. From the money they earned they started their own label, “Rude Records” and soon produced an EP called “No Brains Required” which featured the songs, “No Brains Required”, “Attitude is Everything” and “In With the New”. The sinners disbanded by 1981 with each member starting new acts. They reunited in 2005 with Colin Heddle as the lead guitarist and have been doing reunion gigs in London, Ontario.
