Along the way, Sir David recalls the comedy stars who inspired him, including the pivotal role his friend and mentor Ronnie Barker - the man he calls The Guv'nor - played in his career.
He heads back to the London studios where he was given his big television break, reuniting with future Monty Python star Michael Palin, who he worked with on the 1960s comedy sketch show Do Not Adjust Your Set. Sir David also takes a nostalgic tour of his childhood roots in North Finchley - including a visit to his old school - and is on location on his latest project Still Open All Hours.
The series features exclusive new interviews with many of David's co-stars from more than 50 years on television - including Catherine Zeta-Jones, Nicholas Lyndhurst, Pam Ferris, Michael Palin, Stephanie Cole, Johnny Vegas and Tim Healy.
