At our sessions in SE London we frequently get Rock "Stars" turning up unannounced and joining in/performing in We have recently had Glenn Tilbrooke (Squeeze), Dennis Greaves (Nine Below Zero), Steve Bolton(Atomic Rooster, The Who, Dylan etc), Colin Farley (Cutting Crew) & Dave Kenningham (Folkmob) all turn up and perform acoustic (not their hit stuff - but standard folk or blues))at our sessions in Greenwich and Blackheath. Have any other catters experienced this?
