Leonard Raymond Sipes^[1] (September 28, 1930^[1] – March 14, 2000),^[2] better known as Tommy Collins, was an American country music singer and songwriter.^[1]

Active primarily during the 1950s through the 1970s, Collins was instrumental in helping create the Bakersfield sound of the country music genre. He enjoyed a string of hits during the mid-1950s including "It Tickles" and "Watcha Gonna Do Now".^[1]

Many of the songs he wrote were recorded by other artists. His song "If You Ain't Lovin' (You Ain't Livin')" was a top 10 hit for Faron Young in 1954 and, decades later, hit No. 1 on the chart for George Strait in 1988. In late 1963, Buck Owens released an LP consisting entirely of songs written or co-written by Collins, Buck Owens Sings Tommy Collins, which reached No. 1 on the Billboard Top Country Albums chart in January 1964, holding the top spot for two weeks.^[3]

After several years in the ministry, Collins returned to recording.^[1] In 1965, he had a comeback hit with "If You Can't Bite, Don't Growl".^[1] In the 1970s, he wrote several hits for Merle Haggard and The Strangers, including the No. 1 hits "Carolyn" and "The Roots of My Raising". In June 1980, Haggard recorded a biographical tribute to Collins called "Leonard".

Collins was the inspiration and character talked about in Craig Morgan's song, "I Wish I Could See Bakersfield".

Collins remained active in the songwriting business. In 1999, he was inducted into the Nashville Songwriters Hall of Fame, in a class of inductees that also included Wayne Kemp, A.L. "Doodle" Owens, and Glenn Sutton.^[4] He died March 14, 2000, at his home in Ashland City, Tennessee.^[2]
