Tropic Island Hum by Paul McCartney – ****

First released: 2004

Though recorded years before in 1987 with Linda McCartney doing a fine co-vocal that you’d swear wasn’t her, this song from the cartoon of the same name was released in a truncated form on a single in the UK only. In the US, you can only get the full version of the song as part of "The Music and Animation Collection" DVD.
