Hambleton was the recording engineer when in 1968, Canadian music icon Stompin' Tom Connors, then an aspiring country-folk singer/songwriter, recorded at Toronto's Sound Canada studio to make his debut album, Tragedy Trail, and single, Sudbury Saturday Night.
He was involved with the careers of Rain, a Kitchener pop-rock group featuring Charity Brown which had a Canadian No.

At that time, Toronto band Steel River had released a single "Ten Pound Note" which was the first in the label's catalogue.
Hambleton was due to make a trip to Western Canada to coordinate the promotional arrangement with Quality distributors for the label's roster.
