...a brief excerpt of Nine/Ten's theme tune was playing when The Doctor was talking to the Silurian and Blue Boy about Melody? Thought that was a nice touch.

Ahhhh you know I thought I heard that theme but by the time I noticed it and started listening carefully it stopped. So I didn't imagine it Whereabouts in the episode (time wise) does it happen so I can skip to it on iplayer?

Yeah. Whereabouts is this?

Also a bit of All the Strange Strange Creatures, too. Here's a (slightly dodgy) rip of the mustic from youtube.
