The Spinal Tap Syndrome?

As with Spinal Tap - the movie - which keeps losing their drummers, my band seems to have a problem with keeping our singers. I've had to replace 6 singers in 5 years, and I wonder if this is a sign for me to hang it up.

I'm getting tired of auditioning singers, only to see them leave because they have to pursue higher education, they got other bands and they can't commit to more than one, or they feel incompetent in the band. Sigh.

I'll give this another shot, and hope that the new singer will last longer than our current record for singers. Wish me luck!
