Apart from one mention in a bluegrass discography, I can't dig up anything on The Country Rebels. So, once again, we're forced to rely entirely on the liner notes (edited slightly for length) for information:

"Tommy Beauchamp, leader of the group, was born and raised on a farm in Lafontaine, Ontario. He learned to sing and play guitar at the age of ten...and every day when all his chores were done on the farm, it was pickin' and singin' time for Tommy, not knowing it would mean a career for him in the future...He raises Belgian horses for a hobby, and spends most of his time with them when he and the group are not busy playing. Tommy and Polly, his wife, now reside on a small pioneer farm in the beautiful little country of Lafontaine. Ray Benedict was born and raised in a small farming community near the famous Annapolis Valley of Nova Scotia...His older brothers taught him to play guitar, fiddle and banjo at the age of seven...He moved to Toronto and joined a country group. A few years later he became interested in Bluegrass music, and learned how to play the mandolin...Ray is one of the original members of "The Country Rebels". He now lives by the beautiful shores of Georgian Bay in Perkinsfield, Ontario with his lovely wife and four children. Polly Beauchamp is a country girl all the way. She was born and rasied on a small farm just a few miles from Penetanguishene, Ontario. She comes from a family of twelve, and is the only one in the music field. At the age of nine, Polly started to play guitar for small family gatherings, and by the time she reached the age of fifteen she was performing in public places for dances, parties and friends."

Simply put, Polly Beauchamp is a fantastic singer, and all of the best songs on this 1973 album are the ones she sings (and, in the case of "Rebels-U-Rest" and "A Country Girl I'll Stay", wrote). "Rebels-U-Rest" is one in a long, long line of on-the-road songs, written from the perspective of a musician weary of touring. "Walkin' Shoes" is a traditional bluegrass rave-up sung by all three members. "A Country Girl I'll Stay", my favourite of the bunch, is a lovely ballad about the joys of country life. "And "Bringing Mary Home", an oft-covered bluegrass standard, is a classic Southern gothic ghost story set to music by John Duffey and originally recorded by his group The Country Gentlemen in 1972.
