Four Grammys. Four Billboard #1 blues albums. He toured with the Beatles, backed Bo Diddley and Howlin’ Wolf, and had a song covered by The Blues Brothers. Even had a Top 40 single 40 years ago. Born in Lubbock, Texas, on this day in 1940, Delbert McClinton is still going strong at 80 — winning a Grammy (Best Traditional Blues Album) for his 2019 release “Tall, Dark & Handsome.” Here he is doing his 1980 #8 hit “Givin’ It Up for Your Love.”  And how ’bout a little “B Movie Boxcar Blues” with the Blues Brothers Band — “special just for you.”
