For a faux band, I always thought Spinal Tap were pretty good. Of course their songs are funny, but some of them are no more ridiculous than tunes that were "serious" hits.
I won't lie: I'd love if Spinal Tap played Rocklahoma. Here's the band performing "Stonehenge." One of my favorite parts from This Is Spinal Tap.
Here's the promo for the documentary I mentioned above.
I am so watching this in June. Me, some popcorn and a pint of mint chocolate chip ice cream. Thank goodness for simple pleasures.
