Here's my transcription from the YouTube video. There are still a few gaps indicated by "...". I have "wikified" the terms that I thought could use some explanation.

WHEN I WAS A LAD (LIVERPOOL VERSION)

1. Sittin' in the parlor ... listnin' to the ... sing,
Watchin' me mam on the piano. Boy could she make it ring!
Goin' on the ferry 'cross the Mersey on the deck of the Daffodil,
The Dodgems in New Brighton, it was such a thrill.

CHORUS: When I was a lad, neighbors were neighbors.
When I was a lad, we did each other favors.
Everybody's front door was open; you didn't need a key.
When I was a lad, you could come to our house.
When I was a lad, have a pan of our scouse.
We didn't have much but we were as happy as can be.

2. Goin' for a week down in Butlin's, the ... by the sea
We'd torment the ... of the redcoats, all me mates and me
Ev'ry day in summer was a warm one, off for a paddle or a swim,
Stay out in the fading light till me mam would call us in.

3. Go on with me now to Paddy's Market, buyin' some tripe for tea
Then back for ... on the wireless, sittin' on me granddad's knee.
Goin' to the flicks Sat'd'y mornin', Flash Gordon on the screen.
Getting chucked off the bus by the conductor, and me mam sayin' "Where've you been?"

4. Things aren't quite the same now for most the folks you meet.
Kids would rather play on the computer than ride a bike in the street,
But I still love this city, and the people too.
My heart belongs to Liverpool 'cause that's the place I grew.

AFTER LAST CHORUS:
When I was a lad in Liverpool, that was the place to be,
When I was a lad.
