No, Brian. It's earlier than any Bert influence -- which would have been from mid-late 1950s iirc. I remember the "Was you.." version being sung on a coach carrying the football club I used to play for when I was 16, 67 years ago now. Don't know where & how my team-mates [many of whom happened to be at St Paul's School, as a cousin of mine who was there was main organiser, tho I went to Hendon County myself] got their version from: but, I repeat, their version which has stuck with me ever since, was definitely "Was you ever see..."
