Reading the Wikipedia article about the Foo Fighters and that Dave Grohl re recorded the drums of the second album without telling the drummer because he didn't like his drumming on the recordings.
Reading this I thought, what a shitty thing to do but then I remembered that I did practically the same thing on one of the songs on the first album of my first band. I rerecorded the guitar track without telling our guitar player because it was just too bad. He never said anything so no idea if he didn't notice or didn't want to say anything.
