A spokesman for Lloyd Webber said: 'Really Useful Group (Lloyd Webber's trading company) is interested in buying Warner Chappell, the music publishing arm of Warner Music. Really Useful Group owns probably the greatest and most valuable catalogue of musicals in the world. Unlike much of the rest of the music business, there is no way these musical publishing catalogues can be pirated. There could be fantastic synergies if RUG got together with Warner Chappell.'
