Audio Example 2.4:

Dylan's "Blue Moon" compared with Elvis's 

Compare the opening of Dylan's 1969 recording of the Rodgers and Hart standard with Elvis's 1954 Sun Records version. The keys are identical, suggesting Dylan listened to the Elvis version in the studio right before recording, matching the key exactly. But Dylan's exaggerated croon is arch, even dopey, where Elvis's breathy tone suggests intimate, sexy proximity.
