Answer the question at the end by quoting:

Fogerty was born in Berkeley, California, and grew up in El Cerrito, California, one of five sons born to Galen Robert and Edith Lucile Fogerty. His father, Galen Fogerty, was a native of South Dakota and worked as a Linotype operator for the Berkeley Gazette. Lucile Fogerty was from Great Falls, Montana. When John was two years old his parents both converted to Catholicism.
As CCR was coming to an end, Fogerty began working on a solo album of country & western covers, on which he produced, arranged, and played all of the instruments. Despite the solo nature of the recordings, however, Fogerty elected to credit the album to The Blue Ridge Rangers--a band of which he was the only member. The eponymous The Blue Ridge Rangers was released in 1973; it spun off the Top 20 hit "Jambalaya", as well as a lesser hit in "Heart Of Stone". Fogerty, still using "The Blue Ridge Rangers" name, then released a self-penned rock & roll single": "You Don't Owe Me" b/w "Back in the Hills" (Fantasy F-710). It was a commercial flop, failing to make the Hot 100 in the U.S. Fogerty thereafter abandoned the "Blue Ridge Rangers" identity, and released all his subsequent work under his own name. In early 1974, Fogerty released "Comin' Down The Road"--backed with the instrumental "Ricochet". His first official solo album, John Fogerty, was released in 1975. Sales were slim and legal problems delayed a followup, though it yielded "Rockin' All Over the World", a #27 hit for Fogerty in the United States. In 1977, British boogie rockers Status Quo recorded their version of "Rockin' All Over the World", which became a huge hit and made the song world-famous. Status Quo played it at the opening of the 1985 Live Aid concert. In 1976, Fogerty finished an album called Hoodoo. A single, "You Got The Magic" backed with "Evil Thing", preceded the album's release, but it performed poorly. The album, for which covers had already been printed, was rejected by Asylum Records a couple of weeks before its scheduled release, and Fogerty agreed that it was not up to his usual high standards. Fogerty told Asylum Records to destroy the master tapes for Hoodoo sometime in the 1980s.

what happened in 1985?

Status Quo played it at the opening of the 1985 Live Aid concert.

Some context: A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate traditional musical instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc.; or generate novel electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums. Synthesizers without built-in controllers are often called sound modules, and are controlled via USB, MIDI or CV/gate using a controller device, often a MIDI keyboard or other controller.
A ribbon controller or other violin-like user interface may be used to control synthesizer parameters. The idea dates to Leon Theremin's 1922 first concept and his 1932 Fingerboard Theremin and Keyboard Theremin, Maurice Martenot's 1928 Ondes Martenot (sliding a metal ring), Friedrich Trautwein's 1929 Trautonium (finger pressure), and was also later utilized by Robert Moog. The ribbon controller has no moving parts. Instead, a finger pressed down and moved along it creates an electrical contact at some point along a pair of thin, flexible longitudinal strips whose electric potential varies from one end to the other. Older fingerboards used a long wire pressed to a resistive plate. A ribbon controller is similar to a touchpad, but a ribbon controller only registers linear motion. Although it may be used to operate any parameter that is affected by control voltages, a ribbon controller is most commonly associated with pitch bending. Fingerboard-controlled instruments include the Trautonium (1929), Hellertion (1929) and Heliophon (1936), Electro-Theremin (Tannerin, late 1950s), Persephone (2004), and the Swarmatron (2004). A ribbon controller is used as an additional controller in the Yamaha CS-80 and CS-60, the Korg Prophecy and Korg Trinity series, the Kurzweil synthesizers, Moog synthesizers, and others. Rock musician Keith Emerson used it with the Moog modular synthesizer from 1970 onward. In the late 1980s, keyboards in the synth lab at Berklee College of Music were equipped with membrane thin ribbon style controllers that output MIDI. They functioned as MIDI managers, with their programming language printed on their surface, and as expression/performance tools. Designed by Jeff Tripp of Perfect Fretworks Co., they were known as Tripp Strips. Such ribbon controllers can serve as a main MIDI controller instead of a keyboard, as with the Continuum instrument.
What is a fingerboard controller?
A: A ribbon controller or other violin-like user interface may be used to control synthesizer parameters.

IN: Robert Swan Mueller III (; born August 7, 1944) is an American attorney who served as the sixth Director of the Federal Bureau of Investigation from 2001 to 2013. A Republican, he was appointed by President George W. Bush; President Barack Obama gave his original ten-year term a two-year extension, making him the longest-serving FBI director since J. Edgar Hoover. He is currently head of the Special Counsel investigation of Russian interference in the 2016 United States elections and related matters. A graduate of Princeton University, Mueller served as a Marine Corps officer during the Vietnam War, receiving the Bronze Star Medal with Combat "V" for heroism and the Purple Heart Medal.

Mueller was accepted for officer training in the United States Marine Corps in 1968, attending training at Parris Island, Officer Candidate School, Army Ranger School, and Army jump school. In July 1968, he was sent to South Vietnam, where he served as a rifle platoon leader with Second Platoon, H Company, 2nd Battalion, 4th Marines, 3rd Marine Division. In December 1968, he earned the Bronze Star with 'V' distinction for combat valor for rescuing a wounded Marine under enemy fire during an ambush that saw half of his platoon become casualties. In April 1969, he received an enemy gunshot wound in the thigh, recovered, and returned to lead his platoon until June 1969. For his service in and during the Vietnam War, his military decorations and awards include: the Bronze Star Medal with Combat "V", Purple Heart Medal, two Navy and Marine Corps Commendation Medals with Combat "V", Combat Action Ribbon, National Defense Service Medal, Vietnam Service Medal with three service stars, Republic of Vietnam Gallantry Cross, Republic of Vietnam Campaign Medal, and Parachutist Badge. Mueller eventually became aide-de-camp to 3rd Marine Division's commanding general, then-Major General William K. Jones, where he "significantly contributed to the rapport" Jones had with other officers, according to one report. Reflecting on his service in the Vietnam War, Mueller said, "I consider myself exceptionally lucky to have made it out of Vietnam. There were many--many--who did not. And perhaps because I did survive Vietnam, I have always felt compelled to contribute." After returning from Vietnam, Mueller was briefly stationed at Henderson Hall, before leaving active-duty service in August 1970. He was inducted into the Ranger Hall of Fame in 2004.

did he regret his time serving?
