So here are some suggestions for the "Mention a Ditty" project, courtesy of my man Thanh:
1. Donny Hathaway "Someday We Will All Be Free"

2. John Newton "Amazing Grace"

3. Duke Ellington "Come Sunday" (There was a great cover of this from one of the post-Sept. 11 special at St Patrick's cathedral. The singer just moved me)

4. Tupac "Keep Your Head Up"

Thanks, Thanh!
