The star of the award winning Mark Steel's In Town brings his new, critically acclaimed stand-up show to Radio 4. "I've always known I was adopted, even before I knew where babies who weren't adopted came from." Who Do I Think I Am? is a surprising, moving and incredibly funny story about what Mark discovered in his half-hearted attempt to navigate the red tape required to track down his birth mother. "It never really bothered me that I'd never met my mum. It never occurred to me I needed to meet her to 'find out who I was', as it didn't seem likely I'd discover I was someone different to who I thought I was. Could it turn out I was three stone lighter than I thought, or I spoke Italian or supported Arsenal or had a fear of Liquorice Allsorts? But after the birth of my own son, I realised it's quite an event to have a child, and she may well remember giving birth to me, and maybe even the adoption..." This is a special performance of 'Mark Steel: Who do I Think I Am' - recorded at the BBC Radio Theatre Written and performed by Mark Steel Producer Carl Cooper BBC Studios Production.
