"Memory of a Free Festival" is a 1970 single by David Bowie.
 The song had originally been recorded in September 1969 as a seven-minute opus for Bowie's second self-titled album.
 It was reworked in March-April 1970 at the behest of Mercury Records, the label believing that the track had a better chance of success as a single than "The Prettiest Star", released earlier in the year.
 Bowie and Tony Visconti roughly split the track in half, re-recording it so both halves could function as individual songs.
 A more rock-oriented version than the earlier album cut, this rendition marked guitarist Mick Ronson's and drummer Mick Woodmansey's studio debut with Bowie's band, bringing together the line-up that would shortly record "The Man Who Sold the World".

 Produced by Wright's ex-husband Stevie Wonder, it was released following the former couple's separation and subsequent divorce.

The Cove is a 2009 documentary film directed by Louie Psihoyos which analyzes and questions dolphin hunting practices in Japan.
 It was awarded the Academy Award for Best Documentary Feature in 2010.
 The film is a call to action to halt mass dolphin kills, change Japanese fishing practices, and to inform and educate the public about the risks, and increasing hazard, of mercury poisoning from dolphin meat.
 The film is told from an ocean conservationist's point of view.
 The film highlights the fact that the number of dolphins killed in the Taiji dolphin drive hunting is several times greater than the number of whales killed in the Antarctic, and asserts that 23,000 dolphins and porpoises are killed in Japan every year by the country's whaling industry.
 The migrating dolphins are herded into a cove where they are netted and killed by means of spears and knives over the side of small fishing boats.
 The film argues that dolphin hunting as practiced in Japan is unnecessary and cruel.
