This thread over here, Why Classical Musicians Read Music, included an anecdote about a classical violinist filling in at the last minute for the regular musician who was injured on the day of the performance.
That reminded me of something I’ve often wondered about, with regard to non-classical musical performers, like rock or country music artists. What do they do when a member of the band is injured or falls ill on the day of a performance and is unable to play, yet it would be silly and/or financially unfeaseable to cancel the performance? For the purpose of this question, I’m going to exclude the following:
• bands like Rush where each individual, specific musician is integral to the band’s sound/performance - if you go to a Rush concert, you expect to see Geddy, Alex, and Neil, and so a substitution is out of the question
• injured/ill frontmen or other distinctive focal points, i.e. if Neil Diamond or Britney Spears can’t take the stage, there’s no show
So I’m talking about “side men”, basically. Those guys who back up a solo artist, or even the “lesser” members of a named band. Sure, George Strait has been recording and touring with essentially the same group of “backup” musicians for 30+ years, but the name on the marquee is still “George Strait”, and that’s who people are coming to see. What does George do on the day of a concert when his bass player wakes up and discovers that last night’s chicken must have been bad and he’s too ill to go on stage, or his drummer trips and falls off the drum riser during sound check and sprains his wrist?
Obviously, it would be impractical (and expensive) to carry around a full complement of “reserve” musicians “just in case”, so either the concert is going to be canceled or they’re going to have to quickly hire a substitute. Depending on where they are when the regular musician becomes incapacitated, it might not be possible to fly in a hot studio cat from Nashville in time for the show. So do they, or the promoter, make a hurried search for a suitable local musician to fill in for the night? Any reasonably-sized city should have any number of musicians who could do the job.
Now let’s say they do locate and hire a suitable local to fill in for the night. Because it’s unlikely that this substitute, no matter how talented, is intimately familiar with the artist’s entire repertoire, does that band carry with them some kind of printed scores/lead sheets that they can provide to the substitute so that he can keep up? Speaking for myself as a reasonably competent bass player, I could do the job with nothing more than a lyric sheet with the chords written in (which would be informative enough that I could provide a bass line appropriate to the song, even if it’s not note-for-note identical to the original recording), plus actual notation for any distinctive/signature licks that need to be played exactly. What would I actually be provided with?
