Sounds to me like the guitar is capoed at the 3rd fret and playing in C.
Lovely Rita meter maid
Lovely Rita meter maid
Lovely Rita meter maid nothing can come between us
When it gets dark I tow your heart away
Standing by a parking meter when I caught a glimpse of Rita
Filling in a ticket in her little white book.
In a cap she looked much older, and the bag across her shoulder
Made her look a little like a military man
Lovely Rita meter maid may I enquire discreetly
When are you free to take some tea with me?
(Ah) Rita!
Took her out and tried to win her, had a laugh, and over dinner
Told her I would really like to see her again
Got the bill and Rita paid it, took her home, I nearly made it,
Sitting on the sofa with a sister or two
Oh, lovely Rita, meter maid, where would I be without you?
Give us a wink and make me think of you!
Lovely Rita meter maid
Lovely Rita meter maid
Lovely Rita meter maid
