But if it is an instruction to someone to strike someone or something, rather than to an imagined & personified heavy wind, it would surely require a very powerful blow or strike to "Blow him right back to Liverpool town", but a particularly heavy breeze could, perhaps, poetic-fancifully & hyperbolically, do so? OTOH if it appears that the blow is to be struck by the whole crew acting in concert {whence, the vocative "bullies"}, then maybe by acting together they could hit him hard enough at that, to achieve a similar effect!

Mebbe....
