Why do cover bands attempt to cover Heart?

Shitty camera work and not the best audio, but here is Lisa Guyer covering Barracuda:

Here's a local NH singer, Lisa Guyer singing Straight On. Very good. Sully from Godsmack on drums. She sings on his solo album "Avalon" also. She has a great voice and can sing all sorts of stuff.

Another great job on this one:

I saw Lisa Guyer play with RTZ and Godsmack at the Brad Delp tribute concert in 2007. She is definitely a talented woman.

Wow! wish I had seen that show. She plays solo every Wednesday near me and always sounds amazing. Top notch in my opinion. She's been singing since she was a kid and is very passionate about it and always puts her all into it. You can sense it. She is also very easy to talk to and appreciates her local fans.

I was gonna post that one but the sound quality wasn't as good. Nice job though.
