Yes, it is the original. It was written by Tony Hazzard who wrote a few tunes for Manfred Mann and some other British pop groups like Lulu, The Yardbirds and Herman's Hermits.

Since you cannot copyright a title, it sometimes happens that they get used over again. The title of the old chestnut "Have I Told You Lately That I Love You" was re-used by Van Morrison and that song got Rod Stewart a Grammy.

Todd Snider's "Beer Run" was re-used by Garth Brooks, as was the line, "B, double E, double R, U, N." A little too close to be coincidence. Todd often introduces the song by saying, "I wrote this song and then a few years later some other guys wrote it again."
