I wonder if that’s the same book I have - brown cover with gold printing? Missing most of George Harrison’s songs, but including songs that McCartney wrote for Badfinger?
Yeah, almost every song in that book is in the wrong key. I pretty much learned to play guitar as a teenager by playing along with Beatles records, and I had to go through and write in the correct chords on just about every song.
As for songs affected by tape speeds (or other similar factors), Rush has a couple quirky songs. The first is Xanadu, from the album “A Farewell to Kings”. The entire song is almost a quarter step sharp. This is apparently deliberate; the temple chimes played by Neil Peart at the beginning of the song were apparently a bit sharp, and since the chimes couldn’t be tuned, they either tuned the guitar and bass to the chimes, or else speeded up the tape a bit when it came time to overdub the chimes. So, when playing along with the record, a guitarist or bassist has to retune his instrument for that one song, and then retune again to play the rest of the songs.
The second example is The Camera Eye from “Moving Pictures”. On this song, they seem to have adjusted the tape speed for certain parts of the song, for whatever reason. Perhaps it was decided that slightly speeding up certain sections sounded better. The result is that these sections are ever-so-slightly out of tune with the rest of the song, and a guitarist of bassist just kind of has to grit his teeth and put up with it while playing along because it’s simply not possible to keep retuning while playing.
