A noted professional singer in the Midwest, Malley Keelan is a often-requested tenor soloist in churches and funeral homes, at weddings and other special events. Malley is a Lincoln High School graduate, class of 1966, and received his music degree from the University of Nebraska-Lincoln. Earl "Pete" Jenkins was his voice teacher. While there he sang leading tenor roles in opera and oratorio and was active in the Renaissance music ensemble. Another early interest was participation in the famed Pinewood Bowl productions where he sang leading roles in The Sound of Music; Flower Drum Song and South Pacific.

His Lincoln Light Opera Company was a partner with the Lincoln Civic Orchestra for seven seasons and Malley has been a featured tenor soloist for thirteen seasons with the popular Lincoln Municipal Band summer series, and returned in the summer of 2008 for season fourteen. As founding director and principal tenor of the Lincoln Light Opera Company in 1981 (Gilbert & Sullivan musicals and Americana revues), he produced many dinner theater and concert productions in the 1980s/90s, including The Mikado; H.M.S. Pinafore; Trial by Jury; The Pirates of Penzance and Ruddigore among them.

Under his leadership that ensemble and the Keelan family did over thirty concerts at historic St. Francis Chapel from 1988-1998, raising funds and awareness for its preservation. Upon its purchase by the Roman Catholic Church, the concerts, by now known as Keelan Family & Friends Concerts, became guests in other churches in Lincoln. 2008 will mark the 20th anniversary of the Christmas Celebration concert and will be held at Rosemont Christian Church in Lincoln. The Mother's Day Bouquet of Song concert started in 1998 and the eighth one was in May, 2008, featuring Wilma Sundeen, pianist.

He is the honorary tenor of the Nebraska Maiwand Jezails (named after a type of rifle used by the British army in the mid-1800s), a Sherlock Holmes scholars' dinner club group. His other interests include collecting signed celebrity photographs, primarily of noted classical musicians and film stars of the past. A particular interest in this area are items related to the career and life of John McCormack, Ireland's greatest singer.

Malley has gained recognition as a foremost interpreter of the Irish tenor repertoire and is listed on the John McCormack Society website under the Irish Tenors link, with legendary tenor Frank Patterson, the PBS Irish Tenors, and others. His first recordings were called "Endearing Young Charms" and "A Song for Ireland" and were best-sellers in the 1990s. In March 2006 he released his compact disc entitled "The Old Irish Blessing" featuring "live" and studio recordings from 1983-2001.

Since 1995, he has been a choral conductor in Lincoln churches, notably Southminster UMC; St. Joseph's Catholic Church and Vine UCC. He is also a familiar face and voice on local and statewide public television and AM/FM radio as a performer or interviewer. Since 1993 he has produced "Arts & Interests" on Community Access channel 13 in Lincoln.

From 1979-1996 he owned and operated Keelan's Music Shoppe and Celtic Corner Irish goods. Malley currently operates LarkSong Music Service as an internet and special order service for recorded music and harp sales and rentals.

Malley has now been before the public for forty-five years as a singer. In 2003, he was the recipient of the prestigious Mayor's Leadership in the Arts Award, in honor and recognition of up until then forty years of work as a singer, producer, and music & stage director in many theater, concert, radio and television activities.
