Nazareth is a Scottish rock band, most famous for their international hit song, "Love Hurts" (1975), which can be found on their album "Hair Of The Dog". They also covered My White Bicycle by Tomorrow.
In 1975 they performed Zappa's Road Ladies at a BBC Radio session called At The Beeb. The track got released in 2000 and can also be found as a bonus on the "Hair Of The Dog" re-release from 2010. One of the band members is quoted as saying that they usually played the song as the closing encore because of its jaw dropping effect on the audience- it didn't make them scream for more.
