Moss was born in London, son of Alfred Moss, a dentist of Bray, Berkshire, and Aileen (nee Craufurd). He was brought up at Long White Cloud house on the right bank of the River Thames. His father was an amateur racing driver who had placed 16th at the 1924 Indianapolis 500. Stirling was a gifted horse rider as was his younger sister, Pat Moss, who became a successful rally driver and married Erik Carlsson.
Although ostensibly retired from racing since 1962, Moss did make a number of one-off appearances in professional motorsport events in the following two decades. He also competed in the 1974 London-Sahara-Munich World Cup Rally in a Mercedes-Benz, but retired from the event in the Algerian Sahara. The Holden Torana he shared with Jack Brabham in the 1976 Bathurst 1000 was hit from behind on the grid and eventually retired with engine failure. Moss, at the wheel of the Torana when the V8 engine let go, was criticised by other drivers for staying on the racing line for over 2/3 of the 6.172 km long circuit while returning to the pits as the car was dropping large amounts of oil onto the road. He also shared a Volkswagen Golf GTI with Denny Hulme in the 1979 Benson & Hedges 500 at Pukekohe Park Raceway in New Zealand. In 1980 he made a comeback to regular competition, in the British Saloon Car Championship with the works-backed GTi Engineering Audi team. For the 1980 season Moss was the team's number two driver to team co-owner Richard Lloyd. For the 1981 season Moss stayed with Audi, as the team moved to Tom Walkinshaw Racing management, driving alongside Martin Brundle. Throughout his retirement he raced in events for historic cars, driving on behalf of and at the invitation of others, as well as campaigning his own OSCA FS 372 and other vehicles. On 9 June 2011 during qualifying for the Le Mans Legends race, Moss announced on Radio Le Mans that he had finally retired from racing, saying that he had scared himself that afternoon. He was 81.

Pernell Whitaker (born January 2, 1964) is an American former professional boxer who competed from 1984 to 2001, and has since worked as a boxing trainer. He is a four-weight world champion, having won titles at lightweight, light welterweight, welterweight, and light middleweight; the undisputed lightweight title; and the lineal lightweight and welterweight titles. In 1989, Whitaker was named Fighter of the Year by The Ring magazine and the Boxing Writers Association of America. From 1993 to 1997, The Ring ranked him as the best active boxer in the world, pound for pound.
On February 20, 1999, Whitaker suffered his first convincing defeat against the much bigger, much fresher Felix Trinidad, gamely taking the Puerto Rican the distance in an attempt to win Trinidad's IBF welterweight title. The fight began with both boxers displaying aggressive styles, which included excessive pushing. In the following rounds, both boxers used their jabs most of the time, with Trinidad gaining an advantage when Whitaker attempted to attack inside, eventually scoring a knockdown in round two. In the fourth, fifth and sixth rounds the fighters exchanged combinations. Later in the fight, both boxers fell to the canvas in what were ruled as "accidental slips." On the seventh round, Whitaker displayed more offense, trading power punches with Trinidad, but the champion retained control in the fight's tempo during the eight, ninth and tenth rounds. In the last round, Whitaker, with a badly swollen right eye, displayed a purely defensive stance, avoiding his opponent throughout the round while Trinidad continued on the offensive until the fight concluded. The judges gave the champion scores of 117-111, 118-109 and 118-109. His last fight came on April 27, 2001, against journeyman Carlos Bojorquez. Whitaker, the former lightweight, entered the ring at 155 pounds. He broke his clavicle in round four and was forced to retire; at the time of the stoppage Whitaker was trailing in all the judges' scorecards by 28-29. Following this fight, Whitaker officially announced his retirement. He finished his professional career with an official record of 40-4-1 (17 knockouts). In 2002, The Ring ranked Whitaker as the 10th Greatest Fighter of the Last 80 Years. On December 7, 2006, Whitaker was inducted in the International Boxing Hall of Fame along with contemporaries Roberto Duran and Ricardo Lopez. They were all elected in their first year of eligibility.

When did Whitaker vs. Trinidad take place?

On February 20, 1999,

Bradley Joseph (born 1965) is an American composer, arranger, and producer of contemporary instrumental music. His compositions include works for orchestra, quartet, and solo piano, while his musical style ranges from "quietly pensive mood music to a rich orchestration of classical depth and breadth". Active since 1983, Joseph has performed in front of millions of people around the world. He played various instruments in rock bands throughout the Midwest until 1989 when Greek composer Yanni hired him for his core band after hearing a tape of his original compositions.
Joseph also performed with Sheena Easton for four years as her co-musical director and lead keyboardist. He went from Yanni to Easton and back to Yanni in a few years. "It was a great transition from Yanni because it made me musically aware again", he said in reference to Easton's R&B style. "I went back to where I started but it felt like a new invention." Wheeler questioned how he got hooked up with Easton; Joseph answered that he was recommended by a former road manager. He was included in a try-out with four others, rehearsed with the band, they then cut it down to two, and rehearsed with Sheena for the final cut. Joseph anticipated they would ask him to do a solo on at least one of the songs he was asked to play during the audition, so he wrote a solo for all three songs, which was ultimately the reason he was hired for the job. In a 1995 interview, he said that after five years of touring with Yanni and working on his own debut album, he needed a break. Yanni was still building his career and maintained a hectic concert schedule. Working with Easton, on the other hand, was "the best of both worlds". "She just adopted a baby and is pretty settled in", said Joseph. Tour venues with her included Japan, Indonesia, Puerto Rico, and the United States, as well as routine appearances in Las Vegas and Atlantic City. In March 1995, he appeared with her on The Tonight Show with Jay Leno when she performed her new single at the time, "My Cherie".

What was his relationship with Sheena?
Joseph also performed with Sheena Easton for four years as her co-musical director and lead keyboardist.
