Four 60-something men wearing white tuxedo jackets and red bow ties harmonize The Marcels' version of "Blue Moon" as couples twirl across a dimly lit dance floor.

This is your father's boy band, sporting, perhaps, your father's adult brand.

Pals from Woodrow Wilson High School's Class of '62 formed the doo-wop group four years ago to perform at their 40th reunion. They call themselves the Fabulous Viagras.

The name is a joke, but their dedication to the music is not.

"People were really surprised by how good we were," Jack Andrews said. "They were probably thinking that with a name like ours, it might not be a serious thing."

The success prompted the men to keep the Fabulous Viagras alive. They occasionally perform at charity events, private parties and reunions. Four of the group's five members headlined at the 45th reunion of Woodrow's 1961 class Oct. 14.

"I would have never dreamed they would become the Viagras," said George Theriot, who knew the group members in high school. "They are wonderful. It brings back so many wonderful memories."

Mr. Andrews, Jerry Barnett, Ralph Hamm, Glenn Redmond and Mike Savage met at Lakewood Elementary School. Throughout their school years, various combinations of the five performed together in talent shows and at school dances.

Four of them formed the Embers during their senior year and took second place in a citywide talent show to a band led by Trini Lopez's brother, Jesse. They were later named the winners when Mr. Lopez's group was disqualified because of his professional experience.

The friends maintained contact after graduation, but rarely saw one another.

As the 40th reunion approached, memories started flooding back. In late 2001, Mr. Andrews wondered aloud if they could recapture their high school magic.

"It had been years since any of us had sung except in the shower or in the church choir," he said. "We wanted to see if it was doable."

Mr. Redmond, who received a music degree at the University of North Texas and performed professionally for 10 years, agreed to assess their potential. He enlisted wife Nita, a music teacher, to help.

"She was really skeptical about whether we could sing after 40 years," Mr. Redmond said. "But it just kind of jelled. We just happened to have the right combination of voices."

The group learned about a dozen tunes for their first gig. Mr. Redmond scored each vocal and instrumental part by listening to the records and using a computer software program. He made rehearsal tapes for Mr. Andrews and Mr. Barnett, who do not read music, and Mr. Savage, who lives in Arizona.

"We practiced a lot," said Mr. Barnett, a McKinney pharmacist. "We wanted to be as much like the original recordings as possible. We're much better now. In high school, we just sang what we thought the record sounded like."

Mr. Andrews' brother suggested the group's name, which the men thought was a great joke for the reunion. When they later wanted to change it, their fans rejected the notion.

"That name is something we wanted to get away from, but nobody would let us," Mr. Andrews said. "I just hope we don't get sued."

The Viagras limit their repertoire to doo-wop songs from the late 1950s and early '60s. The style refers to the vocal group harmonies of songs such as "In the Still of the Night" by the Five Satins and "Sixteen Candles" by the Crests.

The music resonates with their generation in ways unlike today's music, said Mr. Hamm, a Dallas insurance executive.

"There was something about these groups," he said. "A number of people are stirred up by this music. It's like coming home."

Said Mr. Andrews: "You're really singing memories."

The group plans to keep singing, but it will always be for fun rather than profit. All five men stay busy with their careers and families. Mr. Andrews owns an advertising company. Mr. Redmond works for an architectural firm. And Mr. Savage is a real estate developer in Arizona.

"I don't know how long we'll keep it up, but we have no plans now to stop," Mr. Redmond said. "I don't know where it will all go, but I don't want to lose the social aspect of it because it's been so fun."
