"Twilight is the grey area of adolescence, where the boy that 'was' confronts the man to 'be' in the shadows. It is also about the confusion, pain, and occasional exhilaration that results from that confrontation."
- Bono on the song 'Twilight'
Many musicians have been influenced by the work of U2. There are several cover versions of U2 songs by bands such as Pet Shop Boys, Pearl Jam and The Chimes, and musicians such as Cassandra Wilson, Joe Cocker and Johnny Cash.
