Carly Simon has a version of “Itsy Bitsy Spider” that segues into a reprise of another song on that album.
Dylan, “Buckets of Rain”
Jackson Browne, “You Love the Thunder (You love the rain)”
Simple Minds, “Don’t You Forget About Me”:
*Will you stand above me?
Look my way, never love me
Rain keeps falling, rain keeps falling
Down, down, down
Will you recognize me?
Call my name or walk on by
Rain keeps falling, rain keeps falling
Down, down, down, down*
And of course A Hard Rain’s A-Gonna Fall.
Sergio Mendes - “Constant Rain”
Matthew Sweet - Thunderstorm
