Together they were 'Vulture Squadron' I think.
Yep the Vulture squadron in “Catch that pigeon”. Thanks I have now got the tune going around and around in my head.

Klunk was the one that built all the strange flying contraptions to catch the messenger pigeon during WWI.
Zilly was the coward who was always trying to get out of flying.
Muttly was the best, always after medals.

Brings back fond memories great cartoon.
