@nottinghillbilly - As already posted by rbmartin on post #51 above there are no Southern services from Forest Hill/Honor Oak Park in either direction on Saturday. And it appears the few bus replacements and the 2 train services after midnight from London Bridge mentioned in that post are no longer calling at Forest Hill either! Southern have advised Journey Planners have now been updated with all planned services for Saturday. These show connections to/from London Bridge using London Overground services to Norwood Junction and then Southern to London Bridge but even if everything runs and to time it's a 28 minute journey so quicker and probably more reliable to use London Overground to Canada Water and the Jubilee line!

London Overground are operating 4 services an hour as they can only operate the West Croydon service due to planned engineering work between Sydenham and Crystal Palace all weekend.
