This fine Carillon I heard first time as an opening piece on a CD from St. Pauls Cathedral, where the Tubas sound wonderful.
I found the score in a fine collection
"Ceremonial Music for Organ"
from OXFORD University Press
I think, the Friesach-horizontal reed makes a good job here. I adjusted it a bit louder (+2.0)
than it is original.
It's a special effect with the final chord without a pedal-note, but with a big crescendo by adding the manual-stops up to full organ. It's very intensive!
I had a look to IMSLP and I found the score there. It is attached below.
