Guests tonight are U.S. soul singer Sharon Jones, vicarious soul sister Meshel Laurie, soulful Mental As Anything frontman Martin Plaza, and the soul of wit, comedian Dave O'Neil.Sharon Jones reveals a captivating previous occupation, Dave nails his one-hit wonders in Know Your Product and Meshel shines in a very different Look What They've Done To My Song Ma.We've also managed to squeeze in a Something's Missing segment featuring more dodgy album covers and if a barking-mad Substitute book doesn't have you enthralled, we wrap it up with a whole bunch of one-hit wonders to reminisce about.
