Harold "Hal" Gefsky, a veteran theatrical agent who worked at APA for more than 25 years, died June 25 in Los Angeles after a long illness. He was 90.

Gefsky, a former vp at APA, represented such clients as Dyan Cannon, Linda Evans, Sharon Tate, Veronica Hamel, Troy Donahue, Gary Merrill, Simon Oakland, Richard Beymer, Robert Clary and Ed Nelson.

Before APA, Gefsky worked at the Mitchell Gertz Agency and had his own theatrical agency. In 1983 he was honored by the Association of Talent Agents with its career achievement award.

"Hal Gefsky will be remembered as a great agent and a true gentleman," APA president and chairman Jim Gosnell said.

A native of Youngstown, Ohio, Gefsky served on the ATA board of directors and was a member of the Academy of Motion Picture Arts and Sciences and the Academy of Television Arts & Sciences.

During World War II, he was a major in the U.S. Army and served on Gen. Dwight Eisenhower's staff in Europe.

Don S. Davis, best known for his recurring role on the TV series "Stargate SG-1," died June 29 of a heart attack at his home in Gibsons, British Columbia, the Vancouver Sun reported. He was 65.

Davis played Maj. Gen. George Hammond for 10 years on "Stargate SG-1" and portrayed two other another military men on TV in "Twin Peaks" (as Maj. Garland Briggs) and in "The X Files" (as the father of agent Dana Scully).

Davis made scores of other appearances in shows including "21 Jump Street" and "MacGyver" and in films including "A League of Their Own," "The Fan" and "Miracle."

Ira Tucker Sr., longtime lead singer of the gospel group the Dixie Hummingbirds, which influenced many performers and backed up Paul Simon on "Loves Me Like a Rock," died June 24 in Philadelphia. Tucker, who had heart problems, was 83.

The Hummingbirds became widely known to Top 40 radio listeners in 1973 when "Loves Me Like a Rock" reached No. 2 on the Billboard chart. The group also produced their own version that year, which won a Grammy for best soul gospel performance.

In 2007, their "Still Keeping It Real" was nominated for a Grammy for best traditional gospel album.

The Hummingbirds trace their history to 1928, when founder James B. Davis formed the group as a student quartet in Greenville, S.C. Tucker was in his teens when he auditioned for Davis in the late '30s.

He was the band's lead singer for decades thereafter. The Vocal Group Hall of Fame, which inducted the Hummingbirds in 2000, said Tucker brought a mixture of gospel and blues to the group's style and added energy and versatility to performances.

In recent years, Tucker collaborated with Wynonna Judd on "How Great Thou Art" and recorded a country album.

Edgar Vincent, who represented Placido Domingo, Beverly Sills, Mikhail Baryshnikov and a bevy of classical music stars during a six-decade career, died June 26 following an operation at Lenox Hill Hospital in New York. He was 90.

Vincent was the primary spokesman for Domingo for the past 20 years. He managed the careers of Sills and Baryshnikov and in recent years also represented bass-baritone Samuel Ramey, violinist Gil Shaham and composer William Bolcom.

Leonard Pennario, a pianist and best-selling classical recording artist, died June 6 at his home in La Jolla, Calif., from complications of Parkinson's disease. He was 83.

Pennario, who won a Grammy in the 1960s for his work with violinist Jascha Heifetz and cellist Gregor Piatigorsky, never attended a music conservatory but at 19 made his debut at Carnegie Hall with the New York Philharmonic.

Pennario made more than 40 recordings for the Capitol record label from 1950-60. He went on to make 20 more for other labels.

An accomplished bridge player, Pennario was once part of a celebrity foursome with comedian Don Adams, bandleader Les Brown and Joan Benny, Jack Benny's daughter.
