"Sgt. Pepper" has been the subject of many tribute albums, including a multi-artist CD available with the March 2007 issue of "Mojo" and a 2009 live album, "Sgt. Pepper Live", by Cheap Trick. Other tribute recordings include "Sgt. Pepper Knew My Father", a multi-artist charity compilation released by the "NME" in 1988; Big Daddy's 1992 album "Sgt. Pepper's", which Moore recognises as "the most audacious" of all the interpretations of the Beatles' LP up to 1997; and the Flaming Lips' "With a Little Help from My Fwends", released in 2014. BBC Radio 2 broadcast "Sgt. Pepper's 40th Anniversary" in June 2007. The programme contained new versions of the songs by artists such as Oasis, the Killers and Kaiser Chiefs, produced by Emerick using EMI's original four-track recording equipment.
