A great vocal performance can elevate an otherwise standard song to amazing heights. Imagine the Who's "Love Reign O'er Me" sung by anybody other than Roger Daltrey or "River Deep, Mountain High" sung by some run-of-the-mill soul singer. It just wouldn't work. If you need any evidence, search YouTube for Audioslave's attempts to perform Rage Against the Machine numbers; Chris Cornell is amazing, but "Bulls on Parade" cannot work without Zack de la Rocha.
