"(I'm a) Road Runner" is a hit song by Junior Walker & the Allstars, and was the title track of the successful 1966 album Road Runner.
[1][2] Walker plays the distinctive tenor saxophone solo, backed by Mike Terry on baritone saxophone with Willie Woods on guitar.
[3] During the recording, it was discovered that Walker could play the song in only two keys.
So Walker sang in a key that he could not play, and after being recorded, the saxophone track was sped up to match.
[4] The pictorial single sleeve used a running bird similar to the Road Runner cartoon character.
