Chris Stamp, a former filmmaker, was the co-manager (with Kit Lambert) and executive producer of The Who until 1973, at which point tensions between Pete Townshend and Lambert caused the management team to be replaced by former assistant Bill Curbishley. Stamp is the younger brother of actor Terence Stamp.
