I listened to the Rockapella version of Sweet Home Alabama, and it is most definitely not the same arrangement as AKA Pella. Although they both use the same bass line, that line is from the original arrangement, and it's expected for acapella groups to adapt intrumental songs to vocals by using some of the same parts.
