Recently, Comstock wrote new big-band arrangements for Brian Setzer's Wolfgang's Big Night Out (2007) and Songs from Lonely Avenue (2009) CDs.

[11] After graduation, Comstock's high school friend, the late trumpeter Uan Rasey, landed a job touring with Sonny Dunham's nationally known dance band.

Doris Day and Frank Comstock began a lifelong friendship while working together in Les Brown's band.

Comstock soon left the Les Brown band to provide arrangements for Doris' first radio gigs: Your Hit Parade and The Rudy Vallee Show.

[8] After joining the Warner Brothers staff in 1947 as a freelance arranger/orchestrator/conductor, Comstock quickly adapted his dance band experience to large orchestras.

Gus Levine and Frank Comstock shared the orchestration work for The Music Man, Finian's Rainbow, and other major films.

Early in the production of Finian's Rainbow, Levine took ill, leaving Comstock to orchestrate all but a few minor scenes.

His original composition The Jade Express and his arrangement of Joanna are featured on Lionel Newman's Exciting Hong Kong LP (available on streaming and music download websites).

Comstock's arrangements also backed recordings and stage performances by Andy Williams, Rosemary Clooney, June Hutton, Herb Jeffries, Margaret Whiting, Connie Haines, Jo Ann Greer, Bob Hope, Steve Lawrence, The Norman Luboff Choir, The Ames Brothers, and other performers.

Three examples of Comstock's orchestral arrangements from movie soundtrack albums are Barbra Streisand's (Just Leave Everything to Me from Hello Dolly!

), Doris Day's (A Woman's Touch from Calamity Jane), and Marilyn Monroe's (Running Wild from Some Like It Hot).

In 2007, Brian Setzer "rediscovered" Frank Comstock and commissioned new arrangements for his Wolfgang's Big Night Out and Songs from Lonely Avenue CDs.
