On the radio all this weekend we're playing some of our favourite cover versions, old & new and rare.

Here are 6 killer covers for your eyes and ears that run the table.

Let's start with one of the best covers that turned out to be one of the best videos ever:

We get tons of phone requests for Bif Naked's take on Metallica's "Nothing Else Matters"

Next up is a cover of a cover...The Foo's cover The Who who covered Mose Alison's original...Young Man's Blues. (Die-hards will remember Roger Daltry's well place "sweeeet f***-all" in the Live at Leeds version....the Foo's took a pass and kept it PG while the cameras rolled on this take)

ANOTHER cover of a cover. "Black Betty" is credited to Ledbelly but the song's history goes back more than a 100 years. Most of us know the 70's version by Ram Jam. A couple of years ago a great version of the song was turned out by an Austrailian band called Spiderbait but we're partial to our Rocksearch Champs, The Standstills' take on this stomper.

Next up is Jacob Moon's one man band cover of Rush's Subdivisions. The guys in Rush were so taken by this version that they invited Moon to perform the song at the Cdn. Songwriter's gala when the song was inducted into their hall of fame. This is AWESOME.

Let's wrap up this up with James Hetfield of Metallica performing Stone Cold Crazy WITH Queen at the Freddie Mercury Tribute Concert at Wembly Stadium. Metallica had just finished recording their own cover of the song which showed up on a Elektra Records Anniversary compilaton. There's lots to watch here....see if you can pick out all the Hollywood & pop & rock stars. After the song is finished Lars & James make some interesting comments....WARNING... strong language... volume down at the end!
