A lot of square dance callers make up 'singing calls' giving the instructions for a dance to the tune, & interspesed with snippets of the original words, of popular songs. The caller Joh Meechan thought that, as he is English, he would use a typically English song from his childhood, rather than an American or Country & Western song.
So he wrote an excellent dance, but does call it now, he got fed up with it being requested too often.
Can't remember all of it but it ends
"You promenade your partner on the bedpost overnight"
