How do you know it's Family Reading Night at William F. Murphy Elementary School? There's a man dressed up as a tree and even the mayor is singing a Lady Gaga tune.

About 150 parents, students and teachers celebrated Family Reading Night at the school Thursday night.

Kevin Toner, the school's social worker, dressed up like a tree in honor of this year's school reading theme, "Fall Into Reading." The costume was designed by Barbara Johnson, the school's art teacher.

Toner said the costume wasn't terribly uncomfortable — he was just "lumbering around."

"I very much enjoy it," Toner said. "The kids get really involved. They love it."

Each student received a book donated by the school's PTO. Students performed poetry and "Book Romance," the school's take on the song "Bad Romance" by Lady Gaga. Families shared stories on mats laid out on the gym floor.

Mayor William F. Murphy and former school principal Clem Campbell both came to the event and sang Lady Gaga along with the students.

Parents at the event said the reading night wasn't just about fun; it also helped improve their children's reading skills.

"I've noticed their reading skills improve when they interact with their friends," said Michael Liaromatis, whose sons are in first, third and sixth grade at Murphy. "It's good for all the kids because they can interact with their friends and read. It's a win-win. They can feel comfortable in school. "

Sue English, whose daughter, Natalie, is in third grade at Murphy, said the reading night helps students feel encouraged to read.

"It's an event that will help children find more comfort in reading than they already do because it involves their family and friends," English said. "Reading is a lifelong friend."

Murphy Principal Susan Futterer said the event is meant to encourage families to spend time reading together.

"We want the children to see that everyone reads," Futterer said. "It's such a warm, great activity to be a part of. We want it to be a regular activity in their household."

Liaromatis said he was happy to participate in the school event.

"My parents never went to school unless I was in trouble," he said. "This is a very family-interactive school, and I'm very happy to be a part of it."
