Kevin McMahon, founder of the Dreamers, said he has many reasons to be happy in 2009.

"Obama won and I'm so happy. The Steelers are going to the Super Bowl and I'm so happy," McMahon said. "The Dreamers are performing their 20th anniversary performance and I'm even happier -- and I just turned 40."

The Dreamers, an all-male a cappella group, will have its 20th anniversary performance at 7:30 p.m. Saturday in 105 Forum. Tickets are $2 for students and $4.99 general admission. More than 50 alumni members are expected to come and perform alongside current collegiate Dreamers members.

"Life is good, and the Dreamers are adding to it," McMahon, Class of 1992, said. "I couldn't have dreamt this would happen."

The performance, which will be one of the Dreamers' largest, will consist of four alumni groups and the current collegiate group, said Michael Macartney, director of the Dreamers.

"We're bookending the performance," Macartney (senior-music education) said. "Then at the end there will be a mass performance with all the groups combined. It's a traditional closer."

Members of the Dreamers are also brothers of the Alpha Zeta chapter of Phi Mu Alpha Sinfonia, a national fraternity with an underlying theme of music, Macartney said.

"A love for music is what brings us together," Macartney said. "It's as much about having a good time as it is about making good music."

McMahon, who founded the Dreamers in 1989, said he never realized the impact the Dreamers had on his life.

"I joined the fraternity as an investment -- I wanted to come back to Penn State and have a connection," McMahon said. "What happened was so much bigger."

With more than 50 alumni members returning for this event, many of them are excited, McMahon said.

"There aren't going to be any 40-year-old men crying or anything. We're all good friends, we want to go back to those times just for fun," he said, adding there's going to be an element of humor at the performance.

Chase Tralka, business manager of the Dreamers, said he's looking forward to this weekend's performance.

"You're going to be able to see how the group has performed over the years -- its history," said Tralka (sophomore-information sciences and technology). "We're really excited about McMahon."

The Dreamers had a 15th anniversary performance, but not nearly as many alumni members were able to come, Macartney said.

"It's a personal thing for me," Macartney said. "I had just joined the Dreamers during the 15th anniversary. Now I'll be graduating soon after the 20th anniversary. I was a Dreamer when I came here, and I'll be a Dreamer when I leave."

The Dreamers have performed for former President George H.W. Bush and have been featured in Seventeen magazine, McMahon said.

"In Seventeen one year, a woman was asked what the most romantic thing anyone has ever done for her," McMahon said. "She answered, 'The Dreamers at Penn State were hired by my boyfriend to sing a valentine to me.' "

The Dreamers dedicated its first CD to the women at Simmons Hall after a performance in front of what was then an all-female dorm, McMahon said.

"A lot of the women came running out and sat along the sidewalk to watch the huge impromptu performance," McMahon said. "The RA had enjoyed the whole concert, but then wrote us up."

The Dreamers have a lot of history and are excited to share it on Saturday, Macartney said.

"Anyone who has come to our shows has asked for more, even though it's not a typical thing to do on a Saturday night," Macartney said.
