Sorry I don't know the answer to your question..(and I did try to google it so this answer wouldn't be completely useless) but without being mean, there is actually a topic to ask questions like this in. You also wrote a spoiler there which is a bit of a sin around these here parts!!
Ok sorry, it looks as though I'm using double standards here! I said it was a spoiler because I didn't know if the thing mentioned was in Monday's episode or in one coming up in the next 2 weeks (the E4 adverts often show clips from a few episodes ahead not just the next one) I haven't seen Monday's yet cos it was on too late so if that was aired on Channel 4, my apologies.
Thanks for all your info people. I have searched the internet but can't find what the song was called. Thanks for looking tho
Regarding other points raised from my post, I was only going off what was in an advert on E4, if that is the case then E4 should be accussed of giving away spoliers!!!!
Well yes, I don't like that they give away so much...but a few people on this board (myself included) switch off when ER ads come on so wouldn't know any of the spoilers...
