There has been speculation about the relationship `` Waltzing Matilda '' bears to an English song `` The Bold Fusilier '' ( a.k.a. `` Marching through Rochester '' , referring to Rochester in Kent , and the Duke of Marlborough ) , a song sung to the same tune and dated by some back to the 18th century but first printed in 1900 .
There is also an idea that tune may be similar to `` The Bold Fusilier '' ( also called Marching through Rochester ) , a song sung to the same tune and dated by some back to the eighteenth century but first printed in 1900 .
