Redirect to file as well as to STDOUT in bash

I've a long bash script with multiple echo statements.

I had a requirement to redirect bash script's output to a file without using redirection from bash shell. I could accomplish that by doing: 

exec 1>>/tmp/output

How do I do something like both redirecting to a file and not stopping to output in STDOUT?

I don't want to edit each and every echo statement to accomplish it.
