Rosalinda "Roz" Doyle is a fictional character on the American television sitcom Frasier. She is played by Peri Gilpin. Roz is the producer of Frasier Crane's Dr. Frasier Crane Show on KACL 780AM. Although initially reluctant to take the job, she and Frasier soon become good friends.

The character is named as a tribute to a producer of the television series Wings (having the same creators as Frasier), who died from breast cancer in 1991.

Lisa Kudrow was originally given the role but was fired before the pilot, in which she was replaced by Gilpin.

Roz was born in Bloomer, Wisconsin on May 5th. Her mother Joanna was a longtime politician there and serves as Attorney General. She has one sibling, a sister, Denise, whose supposedly "perfect" life prompts a great deal of resentment by Roz. Roz's parents are divorced and she maintains relationships with both of them, until her father re-marries a younger woman, which confuses Roz greatly and ultimately ends her relationship with her dad. Her grandmother was an immigrant from Ireland. Frustrated with small-town Wisconsin, Roz moved to Seattle as an adult to pursue a career in radio, and worked in the industry for about ten years before joining Frasier.

Frasier W. Crane, M.D., PhD, A.P.A. is a fictional character on the American television sitcoms Frasier and Cheers. He was played by Kelsey Grammer for 20 years, tying the record for the longest-running character on prime-time American television, which was set by James Arness, who played Marshal Matt Dillon in Gunsmoke. Grammer received Emmy Award nominations for portraying Crane on three different NBC shows, including a 1992 guest appearance on Wings. He made 203 appearances on Cheers and all 264 episode appearances on his spin-off show Frasier.

Glen and Les Charles created Frasier Crane as a temporary love interest for Diane Chambers on their television show Cheers. Cheers and Frasier writer Ken Levine later wrote, "Who would Diane Chambers be attracted to and why? Those were the only considerations." Frasier is introduced in the third season of Cheers (1984–1985) as a rival of Sam Malone. In 1985, Diane leaves Frasier at the wedding altar in Europe, and Frasier begins to regularly attend Sam's bar for drinks. He becomes a friend of Sam and the other bar patrons, and a regular Cheers character. In Cheers, Frasier is said to be an orphan; his mother appears in "Diane Meets Mom" (1984). When Cheers ended in 1993, he moves to Seattle to live with his brother Niles (David Hyde Pierce) and father Martin (John Mahoney) on his own spin-off, Frasier. In "The Show Where Sam Shows Up" (1995), Sam Malone arrives to Seattle to see Frasier, meets his family, and mentions Frasier's inconsistent statements about his family.

Alice May (1847 – 16 August 1887), sometimes known as Louise Allen, was an English singer and actress, perhaps best remembered as the creator of the soprano role of Aline in Gilbert and Sullivan's The Sorcerer (1877).

After musical studies as a child, May studied voice in London with the composer George Benjamin Allen. She began singing in his concerts. May and Allen began to have a relationship, and she traveled with him to Australia in 1870, where they performed together in concerts. Beginning in 1872, May began star in comic operas in Australia. May and Allen returned to England in 1876, where she continued to perform in Offenbach works, earning good notices.

In 1877, May created the role of Aline in The Sorcerer, earning warm reviews, but she left the company after only two months. She quickly returned to Offenbach in London under the management of Richard D'Oyly Carte and, by 1882, she was touring with Emily Soldene's opera company. She split up with Allen and moved to the U.S. in 1883, where she performed first in New York but soon joined Charles Ford's Opera Company in St. Louis and on tour. The next year, she married Louis Raymond, another member of the company. She was earning good notices, but she began to miss performances due to her growing struggle with alcoholism. She continued to perform on tour until 1887, when she became ill and died at the age of 40.
