Have you noticed the abundance of aging classic rockers out on the road this summer? Has made for some truly mind-bending double, triple, even quadruple, bills. Some sound kool ... others made in k-tel hell. just heard of one in particular that's quite ... um ... something: Vanilla Fudge, the Electric Prunes (so far so good, two of my favorites) and ... the Cowsills???? almost worth a trip to vegas to check that one out ... almost.
