I heard on the radio today that "Bohemian Rhapsody" and "Hey Jude" were recorded on the same piano. I went back and listened, and sure enough they sound the same to me.
There's also the legend of "Excalibur" which is a certain Taylor 514 guitar:

There's also Hal Blaine's drum set(s) (combo Ludwigs and Blaemire shells) that was featured of hundreds, if not thousands, of hit songs.
Anyone know of any shared instruments on popular songs? I find this kind of thing interesting.
