 Instead the quadraphonic system on the desk was put to good use for mixing soundtracks for large events, including a celebration of 800 years of the Lord Mayors of London at the Guildhall.Although all the large mixing desks have been dismantled, one smaller desk, a nine-into-three desk used for locations recording, still exists and is in private hands.The small, fully transistorised desk, built around 1958, was used to record "My Old Man's a Dustman" by Lonnie Donegan in 1960.
