I have a collection of real/fakebooks. I studied guitar enough to learn about charts and you can indeed perform from just the chart, though you might not replicate the original performance. Of course, in jazz, improvisation is expected anyway, so as long as you have the changes, the key(s), the meter, and a simple melody line, a band can sound fine. Here for example is John Coltrane's "Giant Steps" https://imgur.com/g633n8b
