that's my favourite "amateur" cover:
YouTube - With or Without You - Sungha Jung
this guy also really knows what he is doing - has a lot of other great U2 covers on youtube
YouTube - U2 City of Blinding Lights Piano Cover
How do you insert youtube links?
YouTube - U2 montage
This guy is freaking awsome! I know it`s not a cover but still,he is worth being noted...
