We sometimes used to walk up Derrydown on the way to Dorrington rd Schools, infants and junior, and used to take the short cut through the right of way at the top of Derrydown. The head teachers at both Schools were Miss Kirkham and Mr Aspinall, probably changed by the time you went there. The Saywells owned a cycle shop somewhere in Aston so perhaps you knew them from when you were there. The son, Renee I think, had a Claud Butler bike which we all lusted after and used to work for Tucker Eyelets back in the mid sixties. Sorry didn't know the Birkins, or at least unable to remember if I did.
