Problem: Background: Bruce Randall Hornsby (born November 23, 1954) is an American singer and pianist. Hornsby draws frequently from classical, jazz, bluegrass, folk, Motown, gospel, rock, blues, and jam band musical traditions. Hornsby's recordings have been recognized on a number of occasions with industry awards, including the 1987 Grammy Award for Best New Artist with Bruce Hornsby and the Range, the 1990 Grammy Award for Best Bluegrass Album, and the 1994 Grammy Award for Best Pop Instrumental Performance. Hornsby has also achieved recognition for his solo albums and performances, his touring band Bruce Hornsby and the Noisemakers, his bluegrass project with Ricky Skaggs and his appearances as a session and guest musician.
Context: Hornsby played more than 100 shows with the Grateful Dead from 1988 until Jerry Garcia's death in 1995. At some shows in 1988 and 1989, he joined the band as a special guest and played accordion or synthesizer. Starting in the fall of 1990, he played piano (and frequently accordion) at many gigs following the death of longtime Grateful Dead keyboardist Brent Mydland, who died suddenly in July 1990. Mydland's place was filled in September 1990 by Vince Welnick, who became the sole keyboardist by March 1992, although Hornsby still sat in with the band on occasion. Hornsby's own music evolved significantly during this time period. Critics have suggested that the Dead's vibrant tradition of melding folk music and the blues with psychedelic rock in "loose-knit expressions" and extended jamming "further pushed [Hornsby] outside the confines of mainstream pop." Critics have also commented upon the "close musical connection" formed between Hornsby and Jerry Garcia, suggesting that Hornsby's particular style of jazz-fueled improvisation added to the band's repertoire, and helped to revitalize and refocus Jerry Garcia's guitar solos in the band's sound. Hornsby's friendship with Garcia continued, both inside and outside the band, as the two "challenged" each other to expand their musicianship through several other album and live collaborations. Above all, Hornsby's musical versatility and ability to slip in and out of extended freeform jams won over longtime Grateful Dead fans. Since his first involvement with the Grateful Dead, Hornsby's live shows have drawn Deadheads and Hornsby has commented: "I've always liked the group of fans that we've drawn from the Grateful Dead time, because those fans are often adventurous music listeners." He has performed a number of their songs at his concerts and as homages on studio and live albums, while Hornsby originals "The Valley Road," and "Stander on the Mountain," appeared several times in the Dead's setlists. Hornsby also co-performed the improvisation "Silver Apples of the Moon" for the Grateful Dead's Infrared Roses. Hornsby was the presenter when the Grateful Dead were inducted into the Rock and Roll Hall of Fame in 1994 and in 2005 he participated in "Comes a Time", a tribute concert to Jerry Garcia. He continues to work with Dead-related projects, such as Bob Weir's Ratdog, Mickey Hart's solo projects. He performed as part of The Other Ones in 1998 and 2000, and on occasion sat in with The Dead. Hornsby continues to be involved in the Grateful Dead and Furthur community, having opened All Good Music Festival in 2012 featured with Bob Weir on rhythm guitar. In mid-2013, Hornsby performed with Grateful Dead-influenced bluegrass group Railroad Earth. Hornsby reunited with surviving members of the Grateful Dead along with Trey Anastasio from Phish and Jeff Chimenti at Levi's Stadium in Santa Clara, California, and later at Soldier Field in Chicago, Illinois, in July 2015.
Question: Was the group already formed when he joined?
Answer: Hornsby played more than 100 shows with the Grateful Dead from 1988 until Jerry Garcia's death in 1995.

Problem: Background: Allison was born December 3, 1937 in Miami, FL. He entered his first race as a senior at Archbishop Curley-Notre Dame High School in Miami. Since he was only 17, he had to have his parents' permission so he thought when his mother said ok, it was forever, but she thought it was for only one race.
Context: Allison moved full-time to the Grand National circuit in 1965 and got his first victory at Oxford Plains Speedway on July 12, 1966. During the course of his career, Bobby Allison accumulated 84 credited victories and 2 uncredited victories making him fourth all-time, tied with Darrell Waltrip, including three victories at the Daytona 500 in 1978, 1982 and 1988, where he finished one-two with his son, Davey Allison. In 1972 he was voted national Driver of the Year for winning ten races and taking 11 poles (including a record 5 straight) and again in 1983 when he claimed his only championship. He was NASCAR Winston Cup Champion in 1983 driving for DiGard Racing. The 1982 Daytona 500 was fraught with controversy that became known as "Bumpergate". He also won the Firecracker 400 in 1982, making Allison the fourth driver to sweep both Sprint Cup point races at Daytona in the same year. Of note, after Allison accomplished this, no driver repeated such a feat until Jimmie Johnson did it in 2013. Allison ran in the Indianapolis 500 twice, with a best finish of 25th in 1975. His NASCAR team owners included DiGard, Junior Johnson & Associates, and Roger Penske, for whom Allison scored four of the five NASCAR wins for American Motors' Matador. The other AMC victory was accomplished by Mark Donohue also racing for Penske in 1973 at Riverside. He raced in NASCAR as a driver/owner of an AMC Matador. Allison was involved in an accident at Talladega in May 1987, that saw his car cut down a tire, turn sideways and go airborne into the protective catch fence that separates the speedway from the grandstands. The impact, at over 200 miles per hour (320 km/h), tore out over 100 yards of fencing. Parts and pieces of the car went flying into the grandstand injuring several spectators. This was the same race where Bill Elliott had set the all-time qualifying record at 212 mph (341 km/h). NASCAR then mandated smaller carburetors for the remaining 1987 events at Talladega and Daytona. The following year, NASCAR mandated restrictor plates at Daytona and Talladega to keep speeds under 200 miles per hour (320 km/h). Allison won the first Daytona 500 run with restrictor plates in February 1988 by a car length over his son Davey Allison, rendering him the first driver to have won the Daytona 500 both with and without restrictor plates. He is the oldest driver (50 years) ever to win the Daytona 500. Bobby and Davey Allison are the first one-two father/son finish in the Daytona 500. As a result of permanent injuries in a crash at Pocono (see below), Bobby now has no memory of the final win of his career or of celebrating together with his son in victory lane. He was elected to the NASCAR Hall of Fame in 2011.
Question: Did he ever have any big crashes during this time?
Answer:
Allison was involved in an accident at Talladega in May 1987, that saw his car cut down a tire, turn sideways and go airborne
