This is such a good series, and this is one of my favourite episodes. Excerpt:
Later in the same interview:
John: But why Elvis?
Costello: That was really picked up by my manager. If you think about the year that I began making records, it was 1977. You had Captain Sensible, Johnny Rotten, Sid Vicious, Rat Scabes … I think I got off quite lightly. Really, it could’ve been much worse.
John: You made a wise choice. I mean, Declan McManus, people would think …
Costello: They’d be expecting a guy in a cable-knit sweater singing whaling songs.
