Glen Campbell's Twisted Double Life!

Singer broke Tany a Tucker’s heart, stole best pal’s wife – but forgot it all before he died

RHINESTONE Cowboy singer Glen Campbell effortlessly fused country and pop music to make elegant, chart-topping hits — but the superstar took a double album’s worth of shocking secrets to the grave!

The Wichita Lineman, whose Alzheimer’s disease robbed him of his memory before his Aug. 8 death at age 81, repeatedly battled booze and drug demons and wrestled with a violent temper — and his passion for Tanya Tucker!

In his 1994 autobiography, Rhinestone Cowboy co-written by Tom Carter, Glen admitted he was a “cheap drunk” and a “cheap high.” While he won a Grammy Award for Gentle on My Mind, the singer was a rough and ready rascal with a short fuse.
