Fans of Sir Ken Dodd are expected to line the streets of Liverpool later to pay their respects to the comedian.
"I couldn't have imagined it would be as it has been," she said. "We've had a tremendous amount of flowers."
She attributed that in part to the "tremendous empathy" her husband had had "with people he knew and people he didn't know".
She told North West Tonight's Roger Johnson: "You look at [the messages] and you know there's so much love there. He loved his audience and he loved what he did."
The Lord Mayor of Liverpool, Cllr Malcolm Kennedy, remembered Sir Ken as "the ultimate showman, a truly unique performer and a wonderful ambassador for Liverpool".
He said last week: "Although Wednesday will be a sombre occasion, it is an opportunity for us all to pay tribute to an unforgettable man."
Flags at the Town Hall, St George's Hall, Cunard Building and Central Library will be lowered for the day as a mark of respect.
