I just wanted to get some opinions of this. I'm in a top 40 cover band that's currently doing gigs and wants to be as professional as possible. I've played and toured with professional bands before so it's not new to me, but it's new to some of the members. The thing that threw me off is that they've been inviting their friends and family to sing songs with the band at our gigs. (Not take over the lead vocals, but as duets and back up singers). To me, it came across a bit karaoke-ish or just a bunch of dudes having fun and jamming more than something a professional band would do. I could be way off so I just wanted some opinions on it, thanks.
