Mike Grady [Barry] who is now a not so young 74 is still acting he turned up in an episode of Endeavour[ Inspector Morse in his early days] and Shakespeare and Hathaway [ A daytime detective set in an around Stratford it's a very light humorous detective series and if you have been to Stratford and surrounding area its worth a watch to spot the locations] last year .He continues to voice a character in the exported version of Thomas the Tank Engine and Friends shown in the US.
Sarah Thomas [Glenda] is 68 did a lot of theatre post LOTSW and Pantomime but there nothing since about 2011 though she may have still done theatre in lesser productions which didn't get press coverage .
Brian Murphy [Alvin] a sprightly 88 still acts in the odd role I remember a series called the Cafe set is Weston Super Mare which was a very gentle watch but he was in a series called Man Down with Greg Davies which I thought was hilarious and has been in Casualty and Holby City his latest role is unsurprisingly "Old Man" in something called Mighty Six which is from this year.
Russ Abbot is 73 no longer a Spy starred in a great series Boomers which I really enjoyed but the BEEB binned it just like they did with LOTSW and Warren . He again may do some theatre but there are no reports in the press for him perhaps he decided to just retire.
Their ages just bring home the stark reality that time is marching on no longer qualify as the younger ones.
