Question: Which song, written by John Lennon, utilizes an anchor point?

Context paragraphs:
Anchor point: In audio and recording, what is known colloquially as an anchor point is a center position in a stereo mix reserved for only three or four important tracks.  Most modern pop productions are anchored by lead (vocals and soloing instruments), bass, kick drum, and snare drum.  These are usually within a few degrees of center (horizontal) and front (proximity or depth) in the mix.  Exceptions include early stereo recordings using "stereo-switching" (a three-way switch allowing only left output, right output, or both) rather than pan pots) such as the Beatles's "Strawberry Fields Forever" and Jimi Hendrix's "Purple Haze".  Examples of tracks using anchor points include The Breeders's "Cannonball", The Cure's "Catch", Lady Gaga's "Just Dance", Lily Allen's "The Fear", Radiohead's "Airbag", Squarepusher's "Star Time 2", Stone Roses's "One Love", and Weezer's "My Name Is Jonas".

John Lennon Museum: John Lennon Museum (ジョン・レノン・ミュージアム , Jon Renon Myūjiamu ) was a museum located inside the Saitama Super Arena in Chūō-ku, Saitama, Saitama Prefecture, Japan.  It was established to preserve knowledge of John Lennon's life and musical career.  It displayed Lennon's widow Yoko Ono's collection of his memorabilia as well as other displays.  The museum opened on October 9, 2000, the 60th anniversary of Lennon’s birth, and closed on September 30, 2010, when its exhibit contract with Yoko Ono expired.  A tour of the museum began with a welcoming message and short film narrated by Yoko Ono (in Japanese with English headphones available), and ended at an avant-garde styled "reflection room" full of chairs facing a slide show of moving words and images.  After this room there was a gift shop with John Lennon memorabilia available.

Life Begins at 40 (song): "Life Begins at 40" is a song by John Lennon.  It was written in 1980, the year that both Lennon and Ringo Starr turned 40 years of age.  Lennon recorded a demo of the song at his home, but it was not recorded at any of the sessions for his comeback album, "Double Fantasy."  Instead, he intended to give the song to Starr to record on his own forthcoming album, "Can't Fight Lightning."  The song's amiable country feel was well suited to Starr's singing style.  After Lennon's murder in December 1980, those plans were shelved.  However, Lennon's demo was eventually issued in 1998 on the "John Lennon Anthology" box set.

Space elevator competitions: A space elevator is a theoretical system using a super-strong ribbon going from the surface of the Earth to a point beyond Geosynchronous orbit.  The center of gravity of the ribbon would be exactly in geosynchronous orbit, so that the ribbon would always stay above the anchor point.  Vehicles would climb the ribbon powered by a beam of energy projected from the surface of the Earth.  Building a space elevator requires materials and techniques that do not currently exist.  A variety of Space Elevator competitions have been held in order to stimulate the development of such materials and techniques.
