who sings the song for that 70s show
That '70s Show Big Star's original version of the song was not used on the show. Instead, a cover version sung by Todd Griffin was used as the theme song for the show's first season. Beginning in the second season, the theme song was performed by the band Cheap Trick. Unlike previous versions of the song, Cheap Trick ended the song with the repeated phrase "We're all alright!" quoting the ending of their 1978 hit song "Surrender".[9]
That '70s Show (season 8) This season also marked a major change in the series, as a new character was introduced to take Eric's place named Randy Pearson (portrayed by new cast member Josh Meyers) and the departure of Michael Kelso, who was portrayed by Ashton Kutcher. Kutcher actually quit the show at the end of season seven but remained on the series for five episodes during the eighth season. He appeared in the first four episodes to give closure to Kelso and he appeared again in the final episode titled "That '70s Finale". Also, Leo (Tommy Chong) returned as a main character since his return to the series in the seventh season (in a special guest role).
