Adam Lambert and cast sing Black Dog (Adam starts wailing at around 1:28)

Slash was the 'mentor' on last night's episode. Adam Lambert does Whole Lotta Love. Wow - he was great. Is it true that Led Zeppelin is legendary for either refusing to license out their music or charging such a high quote that nobody (even their pal Cameron Crowe) can afford much of it. The gossip was told the guys from Zeppelin really, really like Adam Lambert and dropped their quote for him. Anyone know if this is true?

Anyone know why Lester Bangs didn't like Led Zep? Here's a quote from an OLD interview (circa 1980) http://www.cousincreep.com/lester.htm
