I've never seen "Lili Marlene Walks Away" in print so I guess I might have to transcribe it to post it here!Probably Bill's best-known song is "Unicorns" - I know that's been posted here; also his "The writing of Tipperary" was discussed here, and if it wasn't actually posted then there was a link to its words on Suzanne's web site.
He's one of the finest songwriters the UK has produced; I've no problem with putting him on a par with, say, Richard Thompson.
