#1 Song of the Week

This week's song I picked because of sad announcement that Glen Campbell has been diagnosed with Alzheimer's disease.   He getting ready to tour and it will now be his farewell tour, but his wife wanted people to know that if he messes up and flubs words or forgets things its due to Alzheimer's and not to his notorious bouts with alcoholism.
Here is Glen Campbell's first song to top the Billboard Hot 100, from September 1975, 2 weeks at #1


"Rhinestone Cowboy"
