His musical talent was well recognized in his boyhood home of Wilton. There is one folklore story, that the pastor of the First Presbyterian Church of Wilton (Pastor Pollock or McAulay) once saw Gabriel walking in town early in the week. He asked Gabriel if he knew a good song to go along with his sermon. The pastor shared the sermon topic and by the end of the week the boy had written a song for that Sunday, words and music. The Rev. N. A. McAulay was a pastor at the Wilton church for many years, and it is also said that young Gabriel wrote the music for one of McAulay's songs. The song, "How Could it Be," was later published in "Songs for Service", edited by Gabriel, with the music being credited to "Charles H. Marsh," possibly one of Gabriel's pseudonyms.
