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.
