Answer the question at the end by quoting:

P.M. Dawn was an American hip hop act, formed in 1988 by the brothers Attrell Cordes (known by his stage name Prince Be, sometimes credited as Prince Be the Nocturnal) and Jarrett Cordes (known as DJ Minutemix) in Jersey City, New Jersey. They earned significant crossover success in the early 1990s with music that merged hip hop, older soul, and more pop-oriented urban R&B. After recording their debut single "Ode to a Forgetful Mind" in 1988, P.M. Dawn released their first album Of the Heart, of the Soul and of the Cross: The Utopian Experience in 1991 to critical acclaim.
Of the Heart, of the Soul and of the Cross featured the international hit "Set Adrift on Memory Bliss", which sampled the Spandau Ballet song "True", and featured a cameo by Spandau Ballet singer Tony Hadley in the music video of the song. "Set Adrift on Memory Bliss" hit #1 the week of November 30, 1991, and holds the distinction of being the first #1 song on the Billboard Hot 100 chart following the introduction of Nielsen SoundScan to the chart. The song also reached #3 in the United Kingdom. "Paper Doll", which was one of the early singles Island released in the United Kingdom, was released in the US as a follow-up to "Set Adrift on Memory Bliss", and peaked at #28 in early 1992. "Paper Doll" is said well over 100 times in the song, which makes it second only to MC Hammer's "Pray", which holds the record for the most times a title is repeated in a US Top 40 hit (147).  With the success of their debut album, the band parted company with their manager Nick Hemmings and embarked on a world tour. During this world tour, Prince Be gave an interview to Details magazine in which he expressed skepticism of rapper KRS-One's activism: "KRS-One wants to be a teacher, but a teacher of what?" KRS-One and his crew, Boogie Down Productions, responded by storming a P.M. Dawn concert, forcing the group off the stage and performing their songs "I'm Still #1" and "The Bridge Is Over". Defending his actions to USA Today's James T. Jones IV, KRS-One remarked, "I answered his question. 'A teacher of what?' I'm a teacher of respect."  In 1992, P.M. Dawn appeared on the Red Hot Organization's compilation CD Red Hot + Dance, contributing the Richie Rich Mix of "Set Adrift on Memory Bliss". The album, featuring George Michael and Madonna among others, was meant to raise money and awareness in support of the AIDS epidemic.

IN: Randy Randall Rudy Quaid (born October 1, 1950) is an American film and television actor and Academy Award nominee known for his roles in both serious drama and light comedy. He was nominated for a Golden Globe Award, BAFTA Award and an Academy Award for his role in The Last Detail in 1973. In 1978 he co-starred as a prisoner in Midnight Express. Quaid also won a Golden Globe and was nominated for an Emmy Award for his portrayal of U.S. President Lyndon Johnson in LBJ:

In 2004, Quaid appeared on stage undertaking the starring role of Frank in the world premiere of Sam Shepard's The God of Hell, produced by the New School University at the Actors Studio Drama School in New York. In The God of Hell, Quaid's portrayal of Frank, a Wisconsin dairy farmer whose home is infiltrated by a dangerous government operative who wants to take over his farm, was well-received and -reviewed by New York City's top theatre critics. It marked the second time that Quaid starred in a Shepard play, the first being the long running Broadway hit True West.  In February 2008, a five-member hearing committee of Actors' Equity Association, the labor union representing American stage actors, banned Quaid for life and fined him more than $81,000. The charges that brought the sanctions originated in a Seattle production of Lone Star Love, a Western-themed adaptation of Shakespeare's The Merry Wives of Windsor, in which Quaid played the lead role of Falstaff. The musical was scheduled to come to Broadway, but producers cancelled it.  According to the New York Post, all 26 members of the musical cast brought charges that Quaid "physically and verbally abused his fellow performers" and that the show closed rather than continuing to Broadway because of Quaid's "oddball behavior". Quaid's lawyer, Mark Block, said the charges were false, and that one of the complaining actors had said the action was driven by "the producers who did not want to give Randy his contractual rights to creative approval ... or financial participation ..." Block said that Quaid had left the union before the musical started, making the ban moot, and that Quaid only participated in the hearing because he wanted due process. Quaid's statement on the charges was "I am guilty of only one thing: giving a performance that elicited a response so deeply felt by the actors and producers with little experience of my creative process that they actually think I am Falstaff."

did he participate in any other roles?
