You're right, the music at 46:23-46:55, as well 43:01 - 43:34, is from the Secret Machines Live at KCRW EP.46:23 - 46:55 - ?
I may be wrong about it, but I guess this song is some live version or EP version of Nowhere Again, by the Secret Machines
Big networks like the BBC get instrumental mix promos of many popular album releases. Sometimes these get leaked, but if not, they can be hard to come by.Where can I get that specific version? All I can find for download (or just online listening) is the regular version.
48:38 - 49:38 - Harry Gregson-Williams ? Nightmare
