You know what's fun? There are a ton of Jose Feliciano clips on YouTube, footage of him playing over five decades, and he sounds just as fantastic in the recent clips as he does in the old ones.
I tend to find the old ones more fascinating, though, so here he is doing a couple of duets. First, his performance of "Maria Christina" with Dusty Springfield in 1967.
And as if that wasn't enough of a throwback, watch him and Bing Crosby get together a year later to perform "Mama Don't Allow." And listen to him turn the guitar into any instrument he wants - including drums!
