Okay, more on the 1970's and Columbia Records. This act, the first one whose albums I collected (even before I started buying Beatles albums), in its initial 10-year hitmaking period (the only one I care about), quoted the Beatles no fewer than three times in songs. One instance, from the entity's debut album, is an absolutely explicit rendering of one of Lennon-McCartney's most famous lyric lines (the song may as well have said "As John and Paul once told us, ..."), while the other two cases, from among this act's many Top 10 hit singles, use Beatles titles as lines.
Name the act, its three tracks, and which Beatles' lines are quoted.
Big hint: Prior to being signed to Columbia, this act used to actually play "Magical Mystery Tour" live in clubs, which of course The Beatles themselves never actually did (though Paul does now). Coincidentally, this act's only non-self-composed hit from the era was a cover version by someone directly involved in The Beatles' MMT.
And let me know, there may be even more Fab quotations which I haven't thought of.
