I downloaded Queen's concert from 4/29/75 from Shizuoka, Japan (on the site link which seems to no longer have bootlegged concerts, by the way)....and........listening to Liar.......the vocal parts in the middle......wehre Frdiie sing Mama I'm be youre slave.....and thene it is followed by "All Day Long".........is that being sung by John?? it doesnt really sound like Freddie or Brian or Roger.....wondering if anyone that has heard some bootlegs from that era can shed some light on this....
sometimes in the early concertdays,john sneaked behind freddie and shouted this line in his mic.
actually it was the only line john could identify with in any queen-lyric.
