What's that song called? I think its by Jonny Cash cuz it goes "...Johnny Cash, back in '68 he liked to smoke that hash and it keeps going "Lets all get stoned, something something, we'll be higher than a hippy, something something."
Don't know the song Let's All Get Stoned but, the song Let's Get Stoned was by the Coasters in 1965. Also Let's Get Stoned was recorded by: Manfred Mann in 1966; Ray Charles in 1966; The Everly Brothers in 1967; Booker T & the MG's in 1968; Joe Cocker in 1970; Atlanta Rhythm Section in 1979; and many others
