Just thinking out loud. 1. What looks like four pictures of crows of variable background darkness. 2. A Joey in a kangaroo pouch. 3. A scene from MIB with Orion the cat and Laurel (Linda Fiorentino) How to make a song title out of those 3 pics.
Yep edit to add: Your summation of clue 2 contains almost all the syllables I'm looking for (there is an article change.)
Sure they are crows? Because they were birds, a flock of birds, and four times coming to flocks of birds. If they are crows, though, it might be murders.
