Twenty four years before taking up his residency in Emmerdale, Patrick was surprised by Eamonn at a school in London's Earls Court.
The popular actor had scored success in television's Callan and Special Branch and his colleagues from those hit series - Edward Woodward and George Sewell - are on his guest list.

Eamonn disguised himself as a farm hand and rode a horse and cart to the Emmerdale Farm set as the cast gathered for a photo shoot to celebrate the 1000th edition of the soap opera. Dinah Sheridan, Frank Thornton and her brother Brian Rix are among those who pay tribute to Sheila, who has been with the series since its very first episode.

The former pub entertainer and stand up comedian who originally joined the soap in 1978 for a 4 week stint, was surprised by Michael on the set of the show's pub - The Woolpack - while recording a 'dummy' trailer for the show.
Guests include entertainer Marti Caine, cricket umpire Dickie Bird and comedian Jim Bowen.

Another photo shoot for another milestone – this time for the show's 20th anniversary - was interrupted by Michael outside The Woolpack in order to surprise Frazer - another original member of the cast.
Among those greeting him back at the studios of Yorkshire Television are Coronation Street's Bill Waddington and actress Susan George.

Richard, whose career began in British films in the 1950s, appeared briefly in another well known television soap, Crossroads - before joining Emmerdale Farm in 1982. Michael surprised him in The Woolpack, and his guests include actors Muriel Pavlow and Ian Bannen. Unfortunately, Richard suffered a well-publicised heart attack at the after-show party.

This time, the show's 25th anniversary prompts Michael to disguise himself as Santa Claus to surprise the elder Sugden son during filming at West Yorkshire's Wharfedale Hospital.
Clive - who joined the soap in 1980 - is greeted by musicians Gerry Marsden and Rick Wakeman and comedian Ken Dodd.

Christopher - who had been with the soap since 1986 - was surprised by Michael while filming publicity for the release of a new Emmerdale video special in a hotel in central Leeds.
His tribute includes a filmed message from actor Peter O'Toole, with whom Christopher worked with in a National Theatre production of Macbeth.

Michael interrupted the recording of a rainy scene on location outside Emmerdale's Post Office in order to surprise Paula, well known for playing the village busy body - a role she first played in 1994.
Comedian Ken Dodd and actress Brigit Forsyth send recorded messages, while actor Paul Shane and actress Su Pollard greet Paula in the studio.

John - who has played the village vicar since 1996 - was surprised by Michael, appropriately, on the set of the soap's St Mary's Church.
Among the guests who greet John back in the Leeds studios of Yorkshire Television are 'Pet Shop Boy' Neil Tennant and actress Sue Johnston.
