Bob Montgomery, a songwriter and producer who wrote hits for pop and country artists from Buddy Holly to Eddy Arnold, died Dec. 4 in Lee’s Summit, Mo. He was 77.

The cause was Parkinson’s disease, publicist Greg Matusky said.

Bobby LaRoy Montgomery was born in Lampasas, Tex., on May 12, 1937, and spent his teen years in Lubbock, Tex. He initially teamed up with Holly as the rockabilly duo Buddy and Bob in the 1950s, then focused on songwriting for Holly and the Crickets, co-writing “Heartbeat,” “Love’s Made a Fool of You” and “Wishing.”

In 1959, Mr. Montgomery moved to Nashville and later started House of Gold Music. It became a major publishing house, scoring hits for country stars including Alabama, Dolly Parton, Kenny Rogers, Dottie West and the Judds.

He wrote “Misty Blue,” which became a country hit for Arnold in the mid-1960s. About a decade later, the song was a commercial smash for the R&B and soul singer Dorothy Moore.

Mr. Montgomery sold House of Gold Music in 1983 to Warner Bros. He also worked over the years as a producer and record-label executive.
