In my current band:
Two.
I do most of the singing, the drummer sings a few and does a lot of harmony vocals. We had just added a killer bassist, who is also a good vocalist, when the pandemic hit, so I guess I could say three—in a three-man band (although we haven’t played a gig due to ——19). The three of us harmonize well together.
For a brief period, I was in a band that had—no joke—four lead singers, and three different backup singers, none of whom were good harmony vocalists (the whole purpose in a backup vocalist, in my opinion).
When the band formed, it was supposed to be the lead guitarist, who was also a good singer...(he was my younger cousin, who was the “leader of the band”);
I was recruited for guitar/slide guitar/harp and some lead vocals.
His girlfriend was to sing lead vocals as well. His girlfriend (now ex-wife) was/is a fabulous vocalist, should have taken 90% of the lead vocals, with us doing harmonies behind her and singing lead on an odd song here and there...I expressed this opinion, but The Leader did not agree, so it was initially split somewhat evenly, each of us doing about 1/3 of the vocals (with her doing the most)...it worked out well because we could all bounce off each other vocally and musically.
Then the bassist’s wife wanted to sing...not a great singer...but the leader didn’t want to lose the bassist, so we got our first backup singer.
Progressively, during the weekly rehearsals over the next five months, the Leader added a third guitarist (his girlfriend’s uncle, who was a very good guitar player...good enough that I gladly set aside some of my “regular” guitar playing and concentrated more on slide and harmonica).
New guitarist’s wife/aunt of our female lead vocalist wanted to sing. She was good. So now we have the fourth lead singer/third good harmony singer.
At this point, I privately offered the opinion to The Leader that this was getting a little top-heavy and more was not necessarily better. He said he had it under control, and I needed “to just play some harp and just sing here and there...”
Then the drummer’s wife wanted to sing. Not that good...but leader didn’t want to lose the drummer, there was our second bad backup singer who also couldn’t sing harmony.
Then the Bassist’s wife’s best friend wanted to join as singer and maracas (because that’s what we needed—more singers, egos...and maracas!)...she was terrible...but the Fearful Leader couldn’t say no, so there were three backup vocalists...none of whom were good singers and none of which could sing harmony.
The set list had changed significantly, too. It went from being a bluesy/classic soul band to pop, rock, country, a sprinkling of blues and a touch of plastic soul (Modern/90’s R&B). It was a mess, because there was no flow from song to song.
At this point, I asked who was going to either build or rent risers for the freaking choir we were forming.
I was told I was being difficult, and my most recent (and what ended up being my last-ever) incident with alcohol was brought up as a reason the band wasn’t any better.
Real cool, cuz...I’m struggling and entering sobriety (and consequently playing better), and you want to say my alcoholism is the reason your now-crappy band is failing, instead of the fact you won’t say no to anyone except me, and you have Ten People/Seven Singers/Three of Whom Should Never Sing In Public (one of whom shouldn’t even sing in the shower...the poor ears of the rats and alligators in the sewer!) in a band that no longer has a stylistic core.
Since I was told I was being so difficult, I decided to make it easier for them. I quit, with the polite warning that it was going to be a disaster when and if they performed.
They decided not to replace the 15 songs that I sang and/or played a major role in musically (because I wasn’t important and was just “difficult”), and a month or so later had their first gig.
They had to play the now-shortened set list twice, and most of the people left during the first rotation. They couldn’t get a rhythm or vibe going, and I was told all the different styles, genres, voices and levels of (in)competence happening within a 25-song set was unbearable.
