Hard-edged, intimidating agent for several British rock bands of the 1960's and 1970's, such as Small Faces, and The Move, which later evolved into Electric Light Orchestra. Known for his strong-arm tactics and quick temper, he once nearly threw John Hawken out of a window at his Carnaby Street office in London. Hawken, a classically-trained pianist and keyboard player for Arden's group The Nashville Teens, was upset and complaining over the small amounts being advanced the band and was nearly choked to death by Arden at the time as well. Arden later did something similar to rock impresario Robert Stigwood in a dispute over royalties, this time hiring several henchmen to hang Stigwood out of a fourth-floor window.
