Question: which American hard rock band has songs that have been covered by Racer X, Fu Manchu, The Smashing Pumpkins, Sebastian Bach and Fighting Gravity? 
Context: The Last Hard Men were an alternative music supergroup composed of former Skid Row vocalist Sebastian Bach, The Frogs guitarist Jimmy Flemion, The Breeders guitarist–vocalist Kelley Deal, and The Smashing Pumpkins drummer Jimmy Chamberlin. Rotten Apples (The Smashing Pumpkins - Greatest Hits as titled on the album's cover) is a greatest hits compilation album by alternative rock band The Smashing Pumpkins.  In the US, it was released in 2001 along with a bonus disc titled "Judas O".  The album's concluding track, "Untitled", was the Pumpkins' final recording before their breakup.  Completed in the days leading up to the band's farewell concert at the Metro in Chicago, it was also released as a single.  Another notable track is "Real Love"; while previously released on "Machina II/The Friends & Enemies of Modern Music", this was taken from the factory master tapes and, as a result, lacks the pops and clicks inherent in all copies of "Machina II" (which is vinyl sourced). "1979" is a song by American alternative rock band the Smashing Pumpkins.  Released in 1996 as the second single from their third studio album, "Mellon Collie and the Infinite Sadness", "1979" was written by frontman Billy Corgan, and features loops and samples that were uncharacteristic of previous Smashing Pumpkins songs.  The song was written as a coming of age story by Corgan.  In the year 1979, Corgan was 12 and this is what he considered his transition into adolescence.  The song was popular with critics and fans; Allmusic's Amy Hanson called it a "somewhat surprising hit".  The song was nominated for the Record of the Year and Best Rock Performance by a Duo or Group with Vocal at the 39th Annual Grammy Awards, and won an MTV Video Music Award for Best Alternative Video.  In 2012, it was voted the second-best Smashing Pumpkins song by Rolling Stone magazine readers. Blue Öyster Cult (often abbreviated BÖC) is an American hard rock band formed on Long Island, New York, in 1967, whose most successful work includes the hard rock and heavy metal songs "(Don't Fear) The Reaper", "Godzilla" and "Burnin' for You".  Blue Öyster Cult has sold over 24 million records worldwide, including 7 million records in the United States alone.  The band's music videos, especially "Burnin' for You", received heavy rotation on MTV when the music television network premiered in 1981, cementing the band's contribution to the development and success of the music video in modern popular culture. Mean Venus is an American hard rock band from New Jersey.  The quintet consists of 'J' (lead singer and songwriter), Adrian Freyre & Marcelo Cardosa (guitar), Russ Ippoliti (drums), and Chigger (bass).

Originally a ska band called Boy O Boy, Fighting Gravity has incorporated a variety of music into their style, including reggae, rock, and pop.  Fighting Gravity was formed while its original members were attending Virginia Tech.  Originally, the band consisted of guitarist David "Tree" Triano, bassist/vocalist David Peterson, keyboardist Eric Lawson, trumpeter Jim Pennington, trombonist Chris Leitch, and drummer Mike Boyd.  In 1995, Pennington departed and was replaced by saxophonist Karl von Klein.  In 1996, Chris Leitch departed and was replaced by trombonist/percussionist John Utley.  In 1997, Karl von Klein departed, replaced by saxophonist Mike Ghegan.  In 1999, Ghegan departed, replaced by trombonist/turntablist Stefan Demetriadis.  Guitarist Michael Sauri replaced a departed Triano in 2000.  In 2001, a rotation of horns brought saxophonist Kevin Tyser into the section.  The horns were phased out in 2003-2004.  Other former members include guitarists Philippe Herndon, Sinakone Phrakhansa and Rich Stine.  As of 2007, the band has three core members: Schiavone McGee, David Peterson and Mike Boyd. James Joseph Chamberlin (born June 10, 1964) is an American drummer and record producer.  He is best known as the drummer for the alternative rock band The Smashing Pumpkins.  Following the 2000 breakup of the band, Chamberlin joined Pumpkins frontman Billy Corgan in the supergroup Zwan and also formed his own group, the Jimmy Chamberlin Complex.  In 2005, Chamberlin joined Corgan in reforming The Smashing Pumpkins; he eventually left the group in March 2009, though he returned again in 2015 for a summer tour.

"Godzilla" is a song by Blue Öyster Cult from their fifth album, "Spectres".  The lyrics are a tongue-in-cheek tribute to the popular movie monster of the same name.
