Perhaps best known as Garth Brooks' mom, Colleen Brooks passed away at the age of 70 at Deaconess Hospital in Oklahoma City, Okla., over the weekend. Mrs. Brooks had battled cancer for several years, according to an Oklahoma radio station. Like her son, Mrs. Brooks was a recording artist in her earlier years -- having been a regular on the famous Red Foley Ozark Jubilee. Garth's new pop video "Lost In You" was not promoted to country radio at all, but still debuted at No. 62 on Billboard's Country Singles chart.
