Thank you for pointing out that, I didn't realise that Hazlewood was the sole songwriter.
Actually, I believe that this should be attributed to their 1968 collaboration "Nancy & Lee" - the first recording of the song attributed to Hazlewood (even though he featured on Nancy Sinatra's original recording).

When attending https://www.setlist.fm/setlist/murderballads/2020/cultuurcentrum-zoetegem-zottegem-belgium-1398c92d.html some months ago before the song Each Man Kills the Thing He Loves, the singer told a story it was based on a poem by Oscar Wilde and first put to music in a film with Jeanne Moreau singing. Afterwards I noticed that Laibach and Gavin Friday also had sung this song. It was considered a Gavin Friday original.
This is a bit different since the poem was made into a song, while the poems by William Blake are only read.
Maybe I'll ask other moderators what they think about this.

I've noticed that a lot of The Lamb were assigned by other persons.as William Blake cover

The guidelines about poems are not really clear. I'll update the Prayer poem. Thanks for reporting.
