Steadfast SCC Centenary

I am trying to find a group of friends who were members of Steadfast during the 1950s 1960s in the hope that we may be able to arrange a meeting during the Steadfast centenary year. We were all cadet instructors and all had our 21st birthdays in 1963. Names I am particularly looking for are: Jimmy Lock, Geoff Bott, John Cross, Dave Drakeford, John Dickinson, Alan Howe, John Hawkins. If any of these are around or if anybody knows their whereabouts I would very much like to hear from them.
