Could be a problem. If TWL *WERE* still in copyright in the
U.S. and you included about 6 lines in maybe a 60 line poem of
your own you could probably get away with it in the U.S. under the
"fair use" exclusions to the copyright act (but that is for the
judge/jury to decide.) The U.K. has a similar exclusion called
"fair dealing" but it is not as liberal.

If I were the publisher and thinking about selling a book in the U.K.
I would not even call in a lawyer; your poem would be excluded.
