Bob Marley indeed but called Three Little Birds :-
Don't worry about a thing
'Cause ev'ry little thing gonna be alright
Singin', "Don't worry about a thing,
'Cause ev'ry little thing gonna be alright."
Rise up this morning,
Smiled with the rising sun
Three little birds pitch by my doorstep
Singin' sweet songs of melodies pure and true
Sayin', "This is my message to you-u-u.
"Singin'...
(Repeat)
"Don't worry about a thing,
'Cause ev'ry little thing gonna be al-right
