Full disclosure, I have a soft spot for the Bee Gees. I obtained some kind of greatest hits compilation as a child on cassette tape and while disco music is generally detestable, I found a lot of their songs to be quite good.
"How Deep Is Your Love" would have to be up there as far as the group's best work is concerned.
It's a song that transcends the perception that many people have of the Bee Gees as the disposable soundtrack of the seventies. They should be known for more than being the soundtrack for John Travolta and that terrible Sgt. Pepper's movie they made.
This is a very touching song and this rendition by the Red Hot Chili Peppers' John Frusciante is stark and lovely. Also, you can't miss Flea performing a bizarre take on "If You're Happy and You Know It" during the first five seconds.
Next is a rather hilarious version of Elton John's classic "Tiny Dancer" as interpreted by rocker and sometimes comedian Dave Grohl.
This performance comes from the now thankfully defunct Late Late Show with Craig Kilborn–current host Craig Ferguson is infinitely funnier. Dave appears to have just wandered in off the street, not even bothering to spit out his chewing gum before leading the crowd in a rousing rendition of this cut.
This isn't a cover, but it is awesome. As if you needed more reasons to love Dave Grohl, here he is teaching Tenacious D's Kyle Gass how to write a hit.
