Need help finding a song from around the 70's?

I heard this song on the radio and the only part i remember was the end. It literally went doo da do do, do do do do do do, doo da do, do do do doo. i also heard the word sparrow in the song. It was clearly from around the seventies. It was on a station that plays those songs. Id like to know the song and srtist, I appreciate the help, thank you!!
