Found All the Parts is an EP released by Cheap Trick in 1980. It was released on a 10-inch disc as part of Epic Records' short-lived Nu-Disk series. The EP also contained a bonus promotional 7-inch single of "Everything Works If You Let It". Found All the Parts was re-issued in 12-inch format in 1983.
"Day Tripper" was not actually recorded live. While the band had recorded a live cover of the song in June of 1979 in Chicago that was intended for this release, the audio quality of the recording was found to be too poor to use. It was then re-recorded in the studio in March of 1980 with Jack Douglas and the sound of the crowd from the original live recording was added in. "Can't Hold On" was from the concerts the band recorded at Nippon Budokan in 1978 and has since been included on the Budokan II and Cheap Trick at Budokan: The Complete Concert albums. "Such a Good Girl" and "Take Me I'm Yours" were recorded with engineer Gary Ladinsky between December 1979 and January 1980, not 1976 and 1977 as the album claims. Eight other tracks were recorded during the same sessions, which were originally intended to be a "publishing demo". The final versions of most of these recordings are scarce (see outtakes below), while "rough" versions of seven tracks from these sessions were officially released via the "Bun EâÂÂs Basement Bootlegs" YouTube channel. Jack Douglas edited the tracks from these sessions later in January of 1980.
This EP is currently available as bonus tracks to the 2006 remastered re-issue of the All Shook Up album as well as The Epic Archive, Vol. 2 (minus "Can't Hold On") in every region except Japan, where it was re-issued in remastered form on its own in 2003. However, "Day Tripper", "Such a Good Girl", and "Take Me I'm Yours" have since been included as bonus tracks on the Mini LP Blu-spec CD 2 reissue of Dream Police in Japan in 2017, while three songs from the sessions with Gary Ladinsky were included on the All Shook Up Mini LP Blu-spec CD 2 reissue.. The EP was also released on CD combined with Busted in 2010 via reissue specialist Wounded Bird Records.
In 2016, Cheap Trick released the similarly titled four-song Found New Parts EP on Big Machine Records as a limited-edition vinyl disc in 10-inch, rpm format.
