Oil millionaire Nubar Gulbenkian owned an Austin FX4 Brougham Sedanca taxi, with custom coachwork by FLM Panelcraft Ltd as he was quoted "because it turns on a sixpence whatever that is." It is believed that Gulbenkian had three such taxis built, the second of which was sold at auction by Bonhams for $39,600 in 2015. Other celebrities are known to have used hackney carriages both for their anonymity and their ruggedness and manoeuvrability in London traffic. Users included Prince Philip, whose cab was converted to run on liquefied petroleum gas, author and actor Stephen Fry, and the Sheriffs of the City of London. A black cab was used in the band Oasis's video for the song "Don't Look Back in Anger." Black cabs were used as recording studios for indie band performances and other performances in the Black Cab Sessions internet project.
