Sowton, Ian: Imagining Sisyphus Happy
'Imagining Sisyphus Happy' by Ian Sowton.
Trafford Publishing, Victoria, Canada, 2006.
A poem in a group of 8, the group titled 'Fables and Twice-Told Tales', poem 8 on page 37 titled, 'Tewler Among Bruckner Fans' reports observations at (totally fictional!) 'Southwark Cathedral and Docklands Branch of the Anton Bruckner Society', apparently in 1590 (sic), with interjections from hens and roosters, and quotes a poem by Levertov (See Levertov)
If you click on the Amazon link and use the "look inside" feature, you can search for Bruckner and read the poem.
My thanks to Ken Ward for this listing.
