"Cornish Floral Dance" is the third Christmas Night with the Stars sketch from the British comedy series Dad's Army.
The platoon, air raid wardens and a number of ladies from the local Women's Voluntary Service congregate in the church hall to rehearse for a performance of 1911 song The Floral Dance.
The Walmington-on-Sea Home Guard have joined forces with Chief ARP Warden Hodges and ladies from the local WRVS to form a choir and they are practising for an upcoming Christmas concert that they intend to give to wounded troops from the Duke of Cornwall's Light Infantry.
After "winning" a coin toss, Captain Mainwaring has naturally assumed the role of conductor, much to the annoyance of Hodges and then proclaims that they will begin with the Floral Dance.
Subsequently, Wilson then investigates inside the piano, and discovers that Private Walker has hidden a bottle of black market whisky in there.
Cue scenes of Corporal Jones coming in too early on the solo part "Borne from afar on the gentle breeze", followed by the next line which he splits between the platoon members.
When it comes to the final instrument, "Euphonium", he is a platoon member short, at which point Walker suggests "Why don’t we split that up?
Frazer, in thick Scots brogue, says "I ken (know) that's fine, I was just trying to buck up a kind of peely-wally English tune."
They begin again, and it goes fine to the end of the verse - at this point a visual gag occurs which is not discernable via the existing soundtrack, but probably involved the Captain falling off his rostrum and coming back up with glasses and cap askew (a piece of business used regularly in many Dad's Army episodes).
