How many songs are there where the definitive version is the live recording, rather than the studio take that (presumably) preceded it? ‘Definitive’ is of course debatable, so let’s say “the version that would probably get played if the song were to get chosen for The Chain on Radcliffe & Maconie’s evening show on Radio 2″.
A few obvious ones off the top:
Talking Heads, ‘Psycho Killer’, Stop Making Sense over ’77.
Bob Marley & the Wailers, ‘No Woman No Cry’, Live! over Natty Dread.
Otis Redding, ‘I’ve Been Loving You Too Long’, Monterey over Otis Blue.
U2, ‘New Year’s Day’, Red Rocks over War.
