Dame Vera travelled the world, often at great personal risk, to entertain and give hope to the troops with classic songs such as The White Cliffs of Dover and We'll meet again.
Hospital staff joined patients in the reminiscence room on Kingswood Ward, to enjoy musical memories and a 1940s tea party, in tribute to the much-loved performer on her 100th birthday.
Debbie, speaking from her home in the Wolds today, said: "The show went really well".
"Dame Vera Lynn has written a number of iconic songs which many residents are likely to have grown up listening to".
Dame Vera is best known for her 1939 hit We'll Meet Again, which was hugely popular with troops posted overseas and their families back home.
As part of the birthday celebrations, children at Brampton Primary School - Dame Vera's old school in East Ham, east London - sang Happy Birthday to her via Skype.
The Forces' Sweetheart, whose image was projected on to the white cliffs of Dover, said she could not believe she had turned 100 on Monday - but that "time marches on".
The Forces' Sweetheart told the BBC documentary about the stories behind her rise to global fame, including her posting with the Entertainments National Service Association in 1944.
Dame Vera, the oldest living artist to chart, has just Depeche Mode's Spirit and Sheeran's million-selling ÷ album between herself and the summit.
Like all Britons who reach 100, Lynn will receive congratulations from Queen Elizabeth II.
"It is an unprecedented honour to have my birthday marked in such a attractive way and I am truly thrilled by this wonderful gesture", the British singer said in a statement.
"I wonder if she ever heard me on the radio after that".
In historian Simon Webb's book A 1960s East End Childhood, it also states: "The Kursaal also had one of the finest ballrooms in Europe - where Vera Lynn launched her career". It is thought that the album will make her the first singer to have released a new album as a centenarian.
