"Genevieve" - Kay Kendall, drunk as a skunk, playing the eponymous "Genevieve" on the trumpet.

Doris Day, "The Deadwood Stage". At Cropredy festival (UK) a few years ago, the madman who was doing the entr'acte records stuck this on. Of course, the 40 million watt PA wafted it across the whole of Oxfordshire and Northamptonshire. I think he played "Nellie the Elephant" as well - far out man.

Julie Christie singing Bushes and Briars in "Far from the Madding Crowd". Terence Stamp performing Jolly Tinker in the same film, accompanied by Dave Swarbrick. And...Swarb and others (including Martin Carthy?)doing the dance music for the Harvest Home in the mediaeval barn.
