40 years ago today (6/23/80), Pink Floyd released the single”Comfortably Numb” with the B-side “Hey You” from The Wall -two songs that have remained in the upper echelon of the band’s storied catalog. Both these compositions feature some of rock’s all-time greatest guitar solos courtesy of David Gilmour, while Roger Waters penned the lyrics and verse progression. Listen to Pink Floy perform “Comfortably Numb” live during The Wall tour live in 1980..
