Question: Which film was made first My Generation or Pumping Iron?

Context paragraphs:
Pumping Iron: Pumping Iron is a 1977 docudrama about the world of professional bodybuilding, with a focus on the 1975 IFBB Mr. Universe and 1975 Mr. Olympia competitions.  Directed by George Butler and Robert Fiore, it is inspired by a book of the same name by Butler and Charles Gaines, and nominally centers on the competition between Arnold Schwarzenegger and one of his primary competitors for the title of Mr. Olympia, Lou Ferrigno.  The film also features segments on bodybuilders Franco Columbu and Mike Katz, in addition to appearances by Ken Waller, Ed Corney, Serge Nubret, and other famous bodybuilders of the era.

Gary Scalese: Gary Scalese was an American rock musician and the lead guitarist on the Iron City Houserockers first album, "Love's So Tough".  He is credited on Joe Grushecky's Myspace page as "Gary Scalese (R.I.P.)".  He died of natural causes at the age of 38 on Friday, August 24, 1990 in St. Petersburg, Florida.  He is also credited on two compilation albums, "Pumping Iron & Sweating Steel: The Best of the Iron City Houserockers" and "Outtakes And Demos 1975–2003" for work done during the 1975–1979 period.

Love's So Tough: Love's So Tough is a studio album by the Iron City Houserockers.  Released in 1979, the Iron City Houserocker's first album attempts to capture the presence of what was essentially a Pittsburgh bar band playing to a blue collar crowd every night.  While Joe Grushecky's songwriting skills are clearly still developing, his potential is visible in cuts such as "Dance with Me" and "Heros Are Hard to Find".  The general sound of the album is reminiscent of a slightly "harder" Bruce Springsteen, and the heavy use of harmonica would be a distinguishing factor of the Houserockers for several albums to come.  The Chuck Berry song "School Days (Ring!  Ring!  Goes the Bell)" was recorded for the album but was cut from the final release.  The track was then released on "Pumping Iron & Sweating Steel: The Best of the Iron City Houserockers".  The album was reissued in CD format in 1999.

Joe Shepley: Joseph James Shepley (born in Yonkers, New York on August 7, 1930; March 26, 2016) was an American jazz trumpeter.  He worked with Burt Collins, Mike Longo, Duke Pearson and others.  He can be heard in the docudrama Pumping Iron.

Pumping Iron II: The Women: Pumping Iron II: The Women is a 1985 documentary film about female bodybuilding, focusing on several women as they prepare for and compete in the 1983 Caesars World Cup.

Mike Katz: Michael Katz (born November 14, 1944) is a former American IFBB professional bodybuilder and former professional football player with the New York Jets, most famous for his appearance with Arnold Schwarzenegger in the 1977 bodybuilding documentary film "Pumping Iron".

My Generation (2000 film): My Generation is a 2000 film by documentary filmmaker Barbara Kopple that looks at the links between young people who attended the original 1969 Woodstock music festival and those who attended the 1994 and 1999 Woodstock festivities.  Despite the wide generational and cultural gaps between the original attendees and the newer ones, the film finds that there are more commonalities than there are differences.  The movie also captured both the notorious mud-slinging performance of the band Green Day at 1994's festival and the chaotic fires at 1999's concert.  The film features performances by such acts as Joe Cocker, Blues Traveler, DMX, and Limp Bizkit.  "My Generation" premiered as a work-in-progress at the 2000 Sundance Film Festival.

Stand Tall (film): Stand Tall is a 1997 documentary about bodybuilding in the same vein as "Pumping Iron".  The movie centers on Lou Ferrigno's battle with hearing loss and his rise to prominence on the world bodybuilding stage.  Bodybuilding legends Joe Weider and Arnold Schwarzenegger also appear in the film, as well as notable bodybuilders like Robby Robinson.

Ken Waller: Kenny "Ken" Waller (born March 20, 1942) is an American former bodybuilder featured in the 1977 movie "Pumping Iron", which starred Arnold Schwarzenegger.  Waller also won the 1975 International Federation of Bodybuilders (IFBB) Mr. Universe contest in Pretoria, South Africa.  He was known for his curly red hair and freckles — to this day, one of the very rare redheaded professional bodybuilders in the sport — and his graceful, confident posing style.

Pumping Iron &amp; Sweating Steel: Pumping Iron & Sweating Steel: The Best of the Iron City Houserockers is a compilation album by the Iron City Houserockers.  Released in 1992 under Rhino Records, it was at that time the only Iron City Houserockers material available on compact disc ("Love's So Tough" and "Have a Good Time but Get out Alive!"  would not be reissued on CD for another seven years after this compilation appeared).  The disc covers all four of the Iron City Houserockers albums from the late seventies and early eighties and places them in chronological order with a few extra tracks thrown in to make it a worthy buy for collectors.  Tracks 1–5 were taken from "Love's So Tough", with "School Days", a Chuck Berry cover, being an unreleased outtake from that album.  Tracks 6–11 were taken from "Have a Good Time but Get out Alive! ", but with the single edit version of "Junior's Bar".  Tracks 12–15 were taken from "Blood on the Bricks", tracks 16–17 from "Cracking Under Pressure" and "Goodbye Steeltown", a Joe Grushecky single released in August 1984 (after the band had broken up), was included as the final song.  The songs were remastered for compact disc by Bill Inglot.
