We're used to finding bloopers in TV shows and movies, but there are tons of blooper moments in iconic rock songs and pop songs that have been kept in the song, sometimes sounding like they were meant to be there....consider near the end of "Sweet Home Alabama," Lynyrd Skynyrd's Ronnie Van Zant yells (something,) then goddam...he's yelling "donuts, goddam," because, according to those that were there, the band had gone out for food during a late night recording session, and someone had either taken or sat on his donuts, and he was pissed....there's the weird piano sound, and subsequent giggle on the Police's "Roxanne," that was caused by Sting going to sit on a piano not knowing the lid was open, and he sat right on the piano insides....David Lee Roth sang nonsense noises when he forgot some lyrics on Van Halen's "Everybody Wants Some', Ringo's shoe squeaks at the very end of the Beatles' "A Day in the Life", Metallica's Kirk Hammett made a mistake on "Master of Puppets" that the band liked better than the original note...more about these, and a bunch more rock song bloopers, here: https://ultimateclassicrock.com/rock-song-screwups/
