SIX celebrities in their seventies and eighties are sent back to 1975 to see if just one week reliving their heyday could allow them to think themselves younger.

Liz Smith, Lionel Blair, Dickie Bird, Kenneth Kendall, Sylvia Syms and Derek Jameson are immersed in bygone years to discover the power the mind has over the body.

Presented by Mariella Frostup and Dr Michael Mosley, this four-part series looks at how a person’s environment can shape the way they think and feel.

In the first episode, the celebrities begin their journey back in time, travelling to their country retreat in vintage cars with songs from the summer of 1975 playing on the radio.
