Apart from a short month-long break in which original producer Stuart Latham took over for one last stint, Margaret Morris presided over Coronation Street until May, in which she introduced Irma Ogden (Sandra Gough) in late January.
Radical young producer Tim Aspinall took the reins in May and quickly made his mark by writing out several characters including Frank Barlow, Harry and Concepta Hewitt, Jerry and Myra Booth and most controversially, Martha Longhurst, a favourite with viewers who Aspinall chose to kill off in his first episode.
In June, Aspinall chose to give newcomer Irma Ogden a family, and cast Bernard Youens and Jean Alexander in the roles of her parents Stan and Hilda.
Barbara Mullaney also made her first appearance as Rita Littlewood for a single episode in December, eight years before returning as a regular cast member.
Just months after her arrival however, the rest of the Ogden family, Irma's mother Hilda, father Stan and brother Trevor, followed her and moved into number thirteen Coronation Street.
In 1970 the producers of Coronation Street decided to reintroduce the Barlows, but Alan Rothwell, the actor who played David, turned down the opportunity to return as he had found work elsewhere.
Still keen to bring back Irma, the producers decided that instead of splitting the couple, David and two-year-old Darren were to be killed in a car crash off-screen.
Upon arriving back on the Street, Irma was rehired at the Corner Shop by the new owner Maggie Cooke and shared the flat above, her former home, with barmaid Bet Lynch.
In a 2012 episode of "The Corrie Years - After the Street" Sandra Gough was interviewed and finally revealed why she had left so abruptly.
As it turned out, the collapse had been Gus' fault as he'd placed too much weight on the ceiling by using the upstairs as a liquor store, and Len was eventually paid.
Stuart Hodges took over the role of preacher at The Glad Tidings Mission Hall when Leonard Swindley was forced to take a rest after having a minor breakdown.
Hodges left the Street to allow Swindley to take his job back, but returned months later with the news that the Mission was to merge with another in Weatherfield.
Charlie Moffitt moved into number 5 with dog Little Titch and his pigeons to lodge with Minnie Caldwell following the departure of Tickler Murphy.
Charlie made enemies of the female residents when he organised a night of exotic dancers at the club, causing a lot of consternation for the men who visited.
One of the exotic dancers had been a red-haired young lady called Rita Littlewood, who Dennis Tanner took home, though his hopes were dashed when she took to Elsie's bed instead.
He arrived with his family in 1964, but when the Street residents took cover in the Mission hall basement during a bomb scare, 15-year-old Trevor took his opportunity to raid the houses and left for London with the stolen goods.
David Graham was an art teacher at a School of Design where Elsie Tanner took an evening job as a life model.
Sgt Bowden, played by actor James Beck (later known for his role in Dad's Army), was the local police officer in charge of Weatherfield district who appeared intermittently between 1964 and 1967.
He is first seen when, after taking his new post, he introduces himself to the local residents and fines Jack Walker for serving drinks in the Rovers Return pub after hours.
His last appearance came when he caught Steve Tanner, Len Fairclough and Albert Tatlock gambling, but rather than take action, he joined in the game.
Alf appeared infrequently for the next year and played piano for the Coronation Street pantomimes in both 1964 and 1968, when regular pianist Ena Sharples was otherwise engaged.
