Hiccup

Commercials for Toyota's “Time Sales Event” campaign are using, as their musical theme, the familiar pirate song “Early in the morning”, though their instrumental version omits the memorable, haunting refrain:

What will we do with a drunken sailor?
What will we do with a drunken sailor?
What will we do with a drunken sailor?
Early in the morning.

I don't always understand the ways of commercial advertising.
