"Thank God It's Christmas" was mainly written by Queen drummer Roger Taylor. However, when he found himself struggling to come up with a chorus he asked the band's lead guitarist, Brian May, to help him out.
When the pair finished the tune they presented it to Freddie Mercury. It was the vocalist's ability to pull back for that song which Brian May remembers. He told Ultimate Classic Rock
: "(Freddie) loved it and did a beautiful vocal. I think it's just the most understated vocal, and I love it, you know."
