It can't be any coincidence that there's only very little difference between 'drummer' and 'dumber'
In my experience drummers tend to be the most trouble in a band, it's hard to find (and keep) a decent one.
In my daughters musical 'career' she spent much of the time playing as a duo, due to a lack of a reliable drummer. When recording, either her (bass, keyboards, lead vocals - and others!) or Charlie (the guitarist) played the drums, as both were 'good enough' drummers, and had both played drums at gigs sometimes.
Interestingly enough, back in the 70's I built and ran the PA for a band of friends called Avalanche, and we had various drummers, and never with a great degree of reliability. However, the guy who ran the band (the bass player) has recently moved back from Croatia, and has decided to play a gig at a local pub - so is trying to get the band back together. He's borrowed my small PA for rehearsal (first one next Saturday), located the original guitarist (who has never stopped playing), found one of the singers (I doubt he's sung since), and the very first drummer - a guy called 'Andrew Pell' who's name I'd long since forgotten
So I'm going along to the rehearsal, to see how it goes - apparently the gig is on July 20th
