The stars of That '70s Show are reuniting -- at least to perform the show's memorable theme song.
Topher Grace, Ashton Kutcher, Laura Prepon, Mila Kunis, Wilmer Valderrama and Danny Masterson gathered around the piano Tuesday evening for a spontaneous reunion, belting out the lyrics to the 1998-2006 Fox comedy's opening track, "In the Street," which was performed by Big Star.

Valderrama posted a photo of the get-together, featuring the former castmates mid-song, via Instagram on Wednesday. The image has gotten nearly 17,000 likes and more than 860 comments on the photo-sharing site.
Masterson, Prepon and Grace also tweeted about the momentous occasion.
The majority of the cast previously reunited in April 2012 for Fox's 25th-anniversary special.
