There have, to date, been more than 20 documentaries made as part of this upbeat personal biography strand, celebrating widely loved subjects as diverse as Graham Norton and Adele, Michael McIntyre and Bruce Forsyth, Paul O’Grady and Andre Rieu – as well as a handful which picked up on pop cultural phenomena – such as the Mamma Mia, Strictly Come Dancing and Grease Stor(ies). Among the many plaudits they received, none was more warmly welcomed than a voicemail message left at the time The Barbara Windsor Story aired, saying: "Not a snide comment anywhere which is unheard of… you made me look wonderful". It was the now very much-missed Dame Babs herself.
