I think there's at least one version of Bold Fisherman collected in 5/4, and I always think of Death & The Lady in 5/4 as well. Some of them might well be originally in 6/4, dropping a beat on a held note, And some have a 3/4 measure at the end of a line, so it (like much of trad English music) in not totally consistent. But there's a definite 5/4 feel.
