Yes, jigjag, Miss Baker even had a song which included "she knows, you know" in the refrain.
On another topic, I was a little irritated to hear someone with an English accent on Radio 4 repeatedly pronounce "law" as "lah", as Americans do.
I hope that's not the beginning of another unwelcome import. I wonder if I'm right here. I think Americans used to pronounce law and saw much the same as we do up to about 30 years ago, if old songs and media are anything to go by.
