The congregation in the 1920s installed a M. P. Möller pipe organ, Opus 4258, with three manuals and 58 registers (stops).
Homer Clinton Wickline began at Second Presbyterian Church in 1956. He served as minister of music into the time when the Second Presbyterian Church became renamed as the Mulberry Presbyterian Church.
In the 1960s,1970s, and 1980s, he gave an extraordinary number of free organ recitals, in all probability more than any other organist in the history of Allegheny County. Many of these recitals were in Wilkinsburg, at Second Presbyterian and often at St. James Church, and many were in Braddock at the historic St. Michael’s Roman Catholic Church.
Sacred Music carried a notice:
The second annual concert of sacred music by the combined choirs of St. James Roman Catholic Church and Mulberry United Presbyterian Church of Wilkinsburg, Pennsylvania, May 4, 1969, featured the performance of Joseph Haydn’s Mass in Time of War and four motets by George Jeffreys. The combined choirs and orchestra were conducted by Homer Wickline, and Harold Unverferth was organist.
