In 1971, Loggins and Jim Messina released Sittin’ In and, although the album yielded no Top 40 radio hits, “Danny’s Song” received a significant amount of radio airplay. Loggins wrote the song for his brother, Danny Loggins, in 1966 as a senior in high school, when Danny became the father of a boy named Colin – his first son.
“Danny’s Song” was included as the B-side of one of their early single releases, “Nobody But You” (U.S. No. 86, 1972). Loggins and Messina would achieve chart success in 1973 with their song “Your Mama Don’t Dance“, but their version of “Danny’s Song” remains one of their best-known songs through the frequent airplay it received on rock and adult contemporary radio stations.
