[Alvin the chipmunk]

Saw "The Musical Box" in London once. A Genesis tribute who only do the prog-rock early stuff, not the candy-floss pop they came out with when Collins became lead singer. The highlight was hearing the 22 minute "Suppers Ready" played live. In fact the popularity of this band is thought to be one of the reasons for the real Genesis' European tour last year (although Gabriel and Hackett sadly werent present).

Although you are right, a lot of tributes theses days are very shoddy.
