I'd heard of them, but couldn't have named a song by them. I've listened to a fair bit of 'southern rock' over the years, but am not sure I need to hear Freebird or Sweet Home Alabama again :) I played the latter in a band.
A couple of things I noticed in your selections were that the band had three guitarists and two drummers. That is unusual. Also, those videos were uploaded 15 years ago which reminds us how long Youtube has been around.
A southern rock band I got into years ago was the Georgia Satellites. I played this song with a different band.
