iPod "The Scientist" by "Coldplay" missing in UK iTMS?

What happen to the music video "The Scientist" by "Coldplay" on UK iTMS?

I bought the video late last year...

I am recommending it to my friend but we don't cannot find it now.

Can you please help me look for this video?

Thanks.

**Also... is it common for a video / song to be pulled off the Music Store after it has been on sale for some time?
