Two Wilton High School graduates will return when the Princeton University Tigertones present an a cappella performance Saturday, April 12, at 4:30 in the high school\u2019s Little Theater on Danbury Road. Graduates Will and Jack Jankowski are both members of the group, along with Greens Farm Academy graduate Matt McAlpin of Wilton, and look forward to sharing their love of music with their hometown crowd. Tickets may be purchased at the door: $10 for students and seniors, $15 for adults. Founded in 1946, the Tigertones remains one of the oldest and most respected all-male, collegiate a cappella singing groups in the country. The group has toured around the globe, from Rio de Janeiro to Geneva to Glasgow, sharing with audiences the harmony and spontaneity that have become its trademark. In recent years, the group has presented private concerts for such dignitaries as the Governor of Bermuda, the Prime Minister of Israel, and Sir Paul McCartney. It has also entertained at American embassies in Switzerland, Japan, Austria, and Belgium. The group\u2019s repertoire is continually expanding with over 60 songs ranging from Cole Porter to traditional Princeton arrangements, the Temptations to the Beatles, and current pop tunes.
