Interesting. FWIW, it immediately registered to me (in the US) as inappropriate.

I realized I don't know why they would do that, but regardless of why, my first thought was hotheaded stereotype: how quickly an 'escort' could arrive, of boats/aircraft capable of sinking them.

My second thought was that the escort boats could play Queen's "We Are the Champions" [1] over loudspeakers. If it can be many sailors impromptu singing it, all the better.
