Mila Kunis, Ashton Kutcher and most of the young cast from That '70s Show reunited recently and photographed their experience.

Kunis (who played Jackie) and Kutcher (Kelso) reunited with Topher Grace (Eric), Laura Prepon (Donna), Wilmer Valderrama (Fez) and Danny Masterson (Hyde).

"Every once in awhile, friends gather for a 6-part harmony of a Big Star song..." Masterson wrote on his Instagram account along with a photo.

The Big Star song Masterson referred to is the theme song to That '70s Show called In the Street, as performed by Big Star members Alex Chilton and Chris Bell. The photo features the six former co-stars gathered around a piano, each presumably singing the song in unison.

The cast of That '70s Show has kept busy with film and television since the series ended in 2006. Kunis and Kutcher both became movie stars with various successful films like Ted, No Strings Attached, The Butterfly Effect and Friends with Benefits. Additionally, Kutcher is currently one of the leads on Two and a Half Men while Kunis continues to voice Meg Griffin on Family Guy.
