Looking for the name of this song i heard in 1978-9

Would you say without a tune I’m a bit confused (chorus-he’s only waiting)
Are you sure you understand that I’m gonna lose (chorus-he’s only waiting)
Rain it has come. Falling leaves pass me by (chorus-bybybybybyyy)
Chasing the sun, searching the blue summer sky (chorus-kyky kyy)
Caught up in the sithing of a passing fate
Bending with the wind, we don’t want to break (chorus-he’s only waiting)
Chasing the sun, falling leaves pass me by (chours-ahahahaaa)
Rain it has come, searching the blue summer sky (chorus-aaaa yie yie yie)
-Music-
Rain it has come, falling leaves pass me by (chorus-bybybybybyyy)
Chasing the sun, searching the blue summer sky (chorus-kyky kyy)
-Music-
Chorus—Summer sky y y, Summer sky y y, Summer sky y y, Summer sky y y, Summer sky y y , Summer sky y y yyyyyyyyyyyyyyyyy
