I'm sure I remember about 10 years at the Last Night the guest soprano (?) singing Rule Brittannia . As she went into the chorus she unfastened a button at the neck of her dress (which was a draped style) and revealed that she was wearing the Union Flag. Can anyone else remember this, or am I going bonkers?
BOO - I found this quote
"Sarah Walker's Last Night of Proms dress - the moment when she pulled open a fold in her ivory dress to reveal a huge Union Jack. It spawned many imitations before steps were taken to make the Last Night a little less boisterous."
but I can't find a picture or clip.
