The 83 year old star of Eastenders and countless Carry On films died from Dementia in December.
Scott Mitchell, who was married to Dame Barbara for 20 years, was joined at Golders Green Crematorium by the allowed number of family and friends.
“As Covid has denied so many of Barbara’s family, friends and fans a chance to say farewell properly, I wanted to share the order of service to let people be a small part of it,” Mr Mitchell told the PA news agency.
“My heart goes out to every family who have experienced the same restrictions at their loved ones’ funerals.” He added: “I would again like to thank my family, friends, the media and the public for their incredible support and well wishes since Barbara’s passing.”
Tributes and readings were led by Ross Kemp, who played her on-screen son Grant Mitchell in Eastenders in which she played Peggy Mitchell for two decades. Actor and friend Christopher Biggins also gave a reading. Others attending included long term friend Anna Karen (Olive in the classic sitcom On The Buses), David Walliams, Matt Lucas, Jane Moore and Jamie Borthwick.
Many floral arrangements were displayed including one simply reading Babs, another The Dame and another Saucy, one her frequently used cheeky retorts in her many Carry On films.
Frank Sinatra’s On The Sunny Side Of The Street, was playing as Dame Barbara’s coffin was brought into the crematorium and the service featured a recording of Sparrows Can’t Sing from the actress’s 1963 film of the same name.
A JustGiving page set up as a tribute to her and in aid of Alzheimer’s Research UK has raised more than £150,000. Mr Mitchell said that was “beyond anything we may have dreamed of”
