In a past life I was a bass guitarist in a garage band. That didn't last--my musical talent was VERY limited. Lots of reasons at home why it couldn't get developed.
I liked both renditions of the AC/DC standard. I especially liked the little kids getting up and dancing to the celloists' riffs. A Finnish bluegrass-ish unplugged group covering a hit by an Australian band who never found a wall socket they didn't like. Yeah, good fit for this cast bullet site. Rock on, in Toto.
