#4 is Leaving on a Jet Plane - which could be a number of people: Peter, Paul and Mary? John Denver?

#7 is I Can't Stand Losing You, the Police; #8 is Mother and Child Reunion, Paul Simon; #14 is I'm Your Man, Mr Leonard Cohen; #17 is Starman, David Bowie; #20 is The Times They Are a'Changin', Mr Bob Dylan.

And #10 is Bruce Springsteen's Land of Hope and Dreams, which is possibly my favourite Springsteen track, and which I want played at my funeral. A little rough on the congregation, as it's about ten minutes long, but hey.
