All eleven tracks on this album were previously issued on the Vee-Jay Records release Introducing...

But after the group became famous, Vee-Jay, still holding the rights to the early material, was able to reissue them in America and this time the records sold in the millions.

Capitol filed a lawsuit attempting to stop Vee Jay from distributing the tracks, but was unsuccessful.

The mono pressing of the album was made with a two-to-one fold-down of the stereo tapes, as evidenced by John and Paul's vocal collision and chuckle heard in the third verse of "Please Please Me".

So the existence of the vocal error in a mono mix is unique to The Early Beatles as well as a short-lived Capitol Starline 45 rpm single released in October, 1965 and deleted only two months later.
