Thunder in My Heart (song)

"Thunder in My Heart" is a song recorded by Leo Sayer for the album Thunder in My Heart, and originally released as a single in 1977. It reached #22 in the United Kingdom. In the United States, it reached #38 on the Billboard Hot 100, and #35 on the chart Cashbox.

It became a number one hit single in the United Kingdom, when an remix by Meck (titled "Thunder in My Heart Again") was released as a single in 2006 (see 2006 in music). "Thunder in My Heart Again" stayed at number one for two weeks. It also peaked at #7 in the Dutch Top 40, remaining in that chart for seventeen weeks.

The following year, Leo Sayer appeared on Celebrity Big Brother in the United Kingdom, and claimed credit for this song getting to #1 as he said:

"It wasn't just because it was a hot tune, it was all because "Oh my God, it's Leo Sayer"."

After being internationally released, it was shown before the animated movie Ice Age: The Meltdown. In the music video, when the female dancers start dancing, this scene is a homage to Xanadu. When the music video was originally released online, it appeared as it was released. However, one version lacks the scenes featuring Leo Sayer and the accompanying sound effects.
