Query: but only in mono!

Im not drunk, I'm beware that this one is not stereo but mono recording! the beatles reached their popularity in 1964 because of the commercial success they covered the american rock n roll bands in the periode. But this album is a bit tame! many die hard fans are not beware of this.The Beatles was not alone in the music scene but Led Zeppelin & deep purple are definitively much better.
