I happened apon this article late last night, Go figure huh *smile*:

"Manfred Mann hit the U. S. shores as part of the so-called "British Invasion" of 1964 with such British bands as The Beatles, The Rolling Stones, The Kinks, The Dave Clark Five and Herman's Hermits.
The band was asked to write a theme song for the British pop music series, "Ready Steady Go," in 1963. The song, called "5-4-3-2-1," was then released as a single in England, where it peaked at # 5 (with no impact in the U. S.).

"Do Wah Diddy":

Their first hit U. S. single, "Do Wah Diddy Diddy," went straight to # 1 on the Billboard magazine Pop chart, spending two weeks in the top spot. Nearly 40 years later, the happy, fun, uptempo, bubblegummy tune can still be heard on Classic Rock radio.
As recently as 1981, the tune was the centerpiece of the film "Stripes," with new Army recruit Bill Murray singing the song as the troops marched:
"There she was just a walkin' down the street singin' / do wah diddy diddy dum diddy do / snappin' her fingers and a shufflin' her feet singin' / do wah diddy diddy dum diddy do..."

By reaching # 1 with the tune in Fall of 1964, the band charted higher than the # 78 chart position reached earlier that year by The Exciters with the same song. Manfred Mann reached # 2 with the song in England.
"Do Wah Diddy Diddy" was not written by the band. It was written by Jeff Barry and Ellie Greenwich, who already had scored monster hits as songwriters with tunes like "Da Doo Ron Ron," "Then He Kissed Me" and "Be My Baby." They later wrote songs such as "River Deep, Mountain High" and "I Can Hear Music."
