"For me, the music of Larry Kerchner is an oasis of joy in a world where most music comes and goes very quickly. His songs embody the essence of the classic writers in a contemporary fashion. It is lovely to be associated with him," Michael Feinstein said in a statement.

Michael Feinstein’s Great American Songbook Initiative "brings the music of the Great American Songbook to young people today, to preserve it for future generations by creating vocal competitions nationwide." The Mabel Mercer Foundation serves to "both perpetuate the memory and spirit of its legendary namesake, Donald F. Smith, and to stimulate and promote public interest in the fragile and endangered world of cabaret."
