If you don't know about Les Paul's contributions to modern music, well - he pioneered the development and design of the solid-body electric guitar, and more-or-less invented overdubbing, tape delay, phasing effects and multi-track recording (or so says Wikipedia).
And the cat could play too! Just take a look at this clip from his 1953 TV series - Les Paul and Mary Ford at Home and see for yourself.
Supposedly, Paul (born Lester William Polsfuss) owned the original tapes of this long-forgotten TV gem, and was in the process of re-mastering them for re-release.
