My feeling is that the Kipling is rather more mocking of the stay-at-homes (although this may have been greatly helped by having heard Leslie Fish sing this and other Kipling poems - she's no time for any kind of discrimination, that one).

I've done a bit more Googling, and the link above does seem to connect to as much online Kipling as you'll get nowadays.

I wonder - how close is Sebastian to Dan and Oona's ages?
