There are three artists called Greyhound.
1) A Reggae band that had hits in the late 60's and early 70's on the Trojan Record Label. Hits included Black and White, Sky High, I Am What I Am, Dream Lover and more.
Greyhound was originally formed by Danny Smith and Freddie Notes & The Rudies in the late 1960s and released tracks under a variety of names, including the Rudies, the Tilermen and Des All Stars, before settling on the Greyhound name. As the Rudies, the group had hits with reggae versions of Clarence Carter's "Patches" and Bobby Bloom's "Montego Bay."
