Meanwhile, The Doctor observes and listens and he can feel the words and the rhyme of the song uplifting his emotions and rather than feeling bittersweet about Rose and the adventures they've had through space and time in both faces - he's beaming. Like she is sitting right to him with her head on his shoulder and if Angel looks into those brown eyes; she will see it's obvious there are a lot of memories going on and laughs hearts-fully at the end and claps joyously.

"Yes! So do I! Very much! That was brilliant. Absolutely brilliant! Thank you so very much!"

It seems like since The Doctor been in this place that he hasn't felt the warmth in his hearts like this and he's glad to feel it again - not only to be this happy but also as a reminder to not get cold and disconnected.
