This past Friday I went to a bar to hear a blues rock band. I had been in the bar maybe 10 minutes when some guy walked up to me and said "Hey, I have my bass here if you want to play it. It's an Ibanez!!" (like it was the most awesome thing in the world) . I thought ***, who is he, and why is his bass here? After asking a few other folks about him, I discovered that I had met him at another bar a few months ago and he had recently taken up bass. When I later wandered to the other side of the bar, I saw his Ibanez Gio sitting behind the bassist's amp. As a side note, I have a Gio that has been modded and it sounds good, but I don't go around bragging about it.
About halfway through the night, the bandleader asked the guy if he'd like to get up and play a few. He did, and though his playing was passable, it was very basic and certainly no match for the band's bassist. I had to suppress a laugh when he announced that he would always be only second-best to the other bassist. Then he played another, and then another. Then he left the bar.
A little while later, the BL announced that since all members of the band I'm subbing for were in attendance (no, we didn't plan this; I live in a small town and we try to support other musicians), we should get up and play. The bassist asked me "Did you bring your bass or would you like to use mine?" I thought that was an odd question because I have never brought an instrument to someone else's gig. I borrowed his Ibanez, which was a nice SR-series model. If it had been a 5-string I would have offered to buy it. Anyway, we played 2 songs and then sat down.
After the show, I asked the bandleader what was up with Mr. I Brought My Bass To Someone Else's Gig. He rolled his eyes and said that he had made the mistake of offering to let the guy come up once, and now he expects to play at every single show. He had no idea how to stop it now, since the guy is apparently clueless about band etiquette.
I think this event served as a good cautionary tale about letting people get up on stage. As someone earlier stated, there are open jams in most towns. I recently found out that this guy (who I have never seen at a jam) is planning on attending the next show I'm playing and I predict he will show up with his bass in hand. I'm not thrilled about the idea of letting him plug into my amp and twiddling the knobs, but I'm also not sure how to handle it since I'm only a sub for the band and he made their banner.
