When I was shooting "events" I used a Nikon 85mm f1.8. Great lens, always did the job for me. I used a borrowed 105 a few times, it was good too.
I imagine a Canon 85 or 100 would work just as well. I loved that 85mm, used it for everything back in the day. I'd still be using it but it was stolen. D^mn thief knew his stuff, he got a great lens!
BTW, I was shooting 35mm in them days!
