Lonzo and Oscar were an American country music duo founded in 1945 originally consisting of Lloyd "Lonzo" George (1924–1991) and Rollin "Oscar" Sullivan (1919–2012), best known for being the first to perform the 1948 song "I'm My Own Grandpa". George departed in 1950, and Lonzo was later portrayed by Johnny Sullivan (1917–1967) from 1950 to 1967 and by David Hooten from 1967 to 1985, when the band retired (with some final shows performed by Sullivan and first Cleo C. Hogan, then Billy Henson, the latter of which eventually bought the rights to the name). Lonzo and Oscar owned a record label, a recording studio, and a music publishing company. The recording studio and the record label were called "Nugget". The music publishing company was called "Lonzo and Oscar (BMI)". Melba Montgomery's first recordings were released on Nugget Records in the late 1950s through the early 1960s. The songs which Starday Records released by Melba Montgomery in the 1960s came from Nugget Records. Harlan Howard recorded an album with Nugget Records. Danny Harrison, Melba Montgomery, and Darnell Miller wrote for Lonzo and Oscar's publishing company, Lonzo and Oscar (BMI).
