1969 saw several new characters making their debuts on Coronation Street, including Betty Williams, Cyril Turpin, Janet Reid, the Butler siblings Sandra and Bernard, Alan Howard, Janice Langton, Edith Tatlock and Ada Broadbent.
Janice was using her growing friendship with Len as a cover for her relationship with Borstal boy Bob Neale, with whom she stole Dave Smith's car.
When Ray was in hospital in November 1969 recovering from the coach crash in the Lake District, Ena Sharples visited him and revealed she'd tried to trace Janice for him, only to find that she was in a Remand Home.
After Valerie's tragic death in 1971 from an electric shock and house fire, Ken took the twins to Scotland to stay with Edith and Alfred.
Edith later returned to Weatherfield with Ken and decided it would be best to sell their house in Scotland so she and Alfred could stay in Coronation Street.
However, with his marriage to Janet Reid in 1973, Ken began making plans to relocate the twins back to Weatherfield and made enquiries with local schools.
Their wishes put an end to the matter, although their decision did not sit well with Albert Tatlock, who only believed it when Edith told him.
When Peter received bad exams results in 1978 due to not putting in enough effort, Ken brought him back home so he could re-sit them under his supervision.
As the go-to man for many a crisis, Cyril soon got to know the locals and involved himself in community events, including a pub football match and the Rovers Christmas concert, in which he acted as Master of Ceremonies.
Cyril was appalled at his own behaviour and, after facing a disciplinary hearing, resigned from the police, having already entertained the notion earlier that year.
He briefly considered buying into the Corner Shop in 1972 and tried to make Maggie feel guilty by pointing out how Betty had looked after her in the past.
In 1974, Cyril was intending to go to Len and Rita Littlewood's (Barbara Knox) engagement party in The Rovers but collapsed and died outside the house, after suffering a heart attack.
Another key showdown came when Valerie's Uncle Albert, with whom Ken had since started to live with, told him that he did not like Janet, as she disapproved of the twins.
Ada Broadbent was the ancient aunt of Albert Tatlock who he invited to his wedding to Alice Pickins in September 1969.
Upon finding out that the vicar, the Reverend Vernon Lingard, would be driving to the service from Preston, he asked him to collect the old lady from her house at 31 Bloomfield Road, Ecclestone.
At one point, hearing the sound of an engine approaching, they hopefully stood in position to beg a lift... only to see a plane flying overhead.
The pair became involved and eventually got engaged, setting the wedding for May, but it was called off when Sandra found out Ray had been unfaithful with their married neighbour Audrey Fleming.
The Butlers were axed from Coronation Street just months after their arrival, and Sandra's exit storyline was her moving to London.
Bernard arrived in Weatherfield and his aunt Elsie Tanner's house in 1969 from Saddleworth, hot on the heels of his younger sister Sandra after their mother had been taken into hospital.
In July, Alan makes a shock return and pleads with Elsie to take him back, telling her he is ready to commit.
Elsie was devastated by his reckless actions, and Alan agrees to terminate the partnership with Jimmy in order to save their marriage and quit the alcohol.
The Howards moved away, and after tying up loose ends selling the garage back to Billy and renting out the house, Alan last appeared in January 1974.
