Re the use in the Steeleye Span album title, it is stated in an album review (http://www.progarchives.com/Review.asp?id=205726 that in an interview, Tim Hart recalled that "Mr." Reservoir Butler was the source for one of the album songs, but he did not remember which. Since this recollection is at best second hand and possibly third, it may be either garbled or unreliable; it seems that M. Carthy was the one familiar with at least one of the "Mrs" R.B. songs elsewhere, so the true information may be available from that source, if he remembers of course; alternatively there may be songs collected from "Mr" R.B. of course, though I have not located them (the Mainly Norfolk article cited above does hint at this, but exactly to what it is referring is unknown to me).

Cheers - Tony
