... to do so vice versa!
Just stumbled upon Peter Gabriels http://petergabriel.com/media/article/2854/and-ill-scratch-yours/ "Scratch my back and I'll scratch yours" project.
Ever since both, Metallica and U2, have written a song called "One" I had the wish to hear how the bands would have covered the other bands song!
That would make an awesome EP:
"Metallica & U2 - One"
1. One - Written and performed by Metallica
2. One - Written and performed by U2
3. One - Written by U2 and performed by Metallica
4. One - Written by Metallica and performed by U2
