Question: Which singer left The George Duke Band opened for Prince's Parade Tour, the first full tour in Europe by Prince?
Context: Barbra Streisand in Concert is Barbra Streisand's First full tour which ran from 1993 through 1994.  The tour consisted of 26 shows starting on New Year's Eve 1993 in Las Vegas and ended Anaheim, California in July 1994.  The 18 shows that went on sale following the new year concerts in Las Vegas sold out in 1 hour.  This tour was also the first time Barbra toured anywhere in Europe and was the last until her in 2006. This is a comprehensive listing of official releases by Lynn Davis, an American R&B and pop singer.  Although she has not recorded a solo album, she has recorded four albums with four separate band/groups: Twennynine, The Gene Dunlap Band, 101 North, and The George Duke Band.  She has a total of nine singles. The Uplift Mofo Party Tour (also known during 1988 dates as the Monsters Of Funk Tour) was a concert tour by Red Hot Chili Peppers to support their third studio album "The Uplift Mofo Party Plan".  Founding drummer, Jack Irons returned the band the previous year to finish out the band's tour and record the next album, The Uplift Mofo Party Plan, which ended up being the only album and full tour to feature the four founding band members: Anthony Kiedis, Flea, Hillel Slovak and Irons.  It was the band's biggest tour at the time and featured their first trip to Europe.  Kiedis, who started to develop a major drug problem on the previous tour, started to fall deeper into his addiction and Slovak's addiction to heroin only grew stronger as well.  Slovak died of a heroin overdose a few weeks after the end of the tour on June 25, 1988.  The surviving three members regrouped for a small boat trip with then manager, Lindy Goetz.  It was there that Irons decided he could no longer deal with being in the band and Slovak's death was too hard for him to handle so he decided to quit the band again, this time for good. The Parade Tour (also called the Under the Cherry Moon Tour ) was a concert tour in support of Prince and The Revolution's eighth studio album "Parade" and his 1986 film "Under the Cherry Moon".  The Hit n Run Tour wasn't a full scale American tour, but a string of concerts that was dubbed "Hit n Run" by Prince's manager.  Most of those shows were announced days or hours before the actual concert took place.  The Parade Tour marked the first full tour of Europe by Prince.  It also saw the expanded Revolution line-up and featured Sheila E. and her band as an opening act for most shows. The Diamonds and Pearls Tour was a concert tour by American recording artist Prince and The New Power Generation promoting his "Diamonds and Pearls" album, released the previous year.  The tour itinerary were scheduled dates in Asia, Europe, and for the first time, Australia.  Like several of his then-recent tours, Prince chose not to tour the United States, the exception being the Lovesexy Tour in 1988.  It would be 1993's Act I Tour before Prince did a full tour of the United States. Lynn Davis (born July 12, 1958) is an American singer, songwriter, musician, and record producer.  She rose to prominence after joining The George Duke Band in 1977.  During her time with the band, she sang lead vocals on their one of their biggest hits; "I Want You for Myself", "Party Down", and "Reach Out".  Under the guidance of Epic Records musician and mentor George Duke, Davis continued booking success by contributing background vocals and writing songs for many singers including Tracie Spencer, La Toya Jackson, Patrice Rushen, Anita Baker, and many other singers. The Hunting Party Tour was the eleventh concert tour by American alternative metal band Linkin Park.  It was launched in support of Linkin Park's sixth studio album, "The Hunting Party" (2014).  The tour was partially announced in May 2014 through a teaser released after the release of trailer of a co-headlined tour "Carnivores Tour" by Linkin Park and Thirty Seconds to Mars.  Later, the tour was officially announced on November 23 with a whole trailer in promotion.  Its first leg under the name "European Tour" began on May 30, 2014, in Lisboa, Portugal, and ended on June 14 in Castle Donington, England, where they played "Hybrid Theory" as a whole album.  The tour features special guests Of Mice & Men and Rise Against.  On January 15, 2015, the band begun the "world" tour for The Hunting Party with the first leg under "North American Tour".  During a show at Indianapolis, Chester Bennington injured his leg, which led to the cancellation of the tour "North American Tour".  The band continued the world tour on May 9, performing at the first edition of Rock In Rio in America.  It is the last full tour to feature Chester Bennington as vocalist before his death in 2017. The Nude Tour was a greatest-hits concert tour by Prince.  While the previous tour drew critical praise, the high cost of the concert tour production made it a financial disappointment; thus, Prince eliminated much of the excessiveness of the previous tour to be more financially viable.  Like several of his then-recent tours, with the exception of Lovesexy, Prince chose not to tour in the United States.  It wouldn't be till 1993's Act I Tour that Prince did a full tour of the U.S. Sheila Cecelia Escovedo (born December 12, 1957) better known under the stage name Sheila E., is an American percussionist, singer, author, and actress.  She began her career in the mid 1970s as a percussionist and singer for The George Duke Band.  After leaving the group in 1983, Sheila began a successful solo career, starting with her critically acclaimed debut album, which included the career-defining song, "The Glamorous Life".  She became a mainstream solo star in 1985 following the success of the singles, "The Belle of St. Mark", "Sister Fate", and "A Love Bizarre" with the latter becoming one of her signature songs.  She is commonly referred to as The Queen of Percussion. The Mother's Milk Tour (also known as the Suckle Up to the Breast of Mother Earth Tour, Positive Mental Octopus Tour, The Lazy Cowgirls Tour and The Great Expectorations Tour) was a worldwide concert tour by Red Hot Chili Peppers to support their fourth studio album "Mother's Milk", the breakthrough album for the band which launched them to bigger success than ever before.  It was the first full tour with guitarist John Frusciante and drummer Chad Smith, who joined late in the previous year.
