How to remove filename from output file?

Hello,
I am trying to print searched multiple keywords in multiple files.
It is almost okay with the code but the code puts filename in front of each line.
How may I get rid of it?

Code:
-grep -A1 'word1' *.txt | grep -A1 'word2' | grep -A1 'word3'

I expect:
Quote:
word1 word2 word3
how are you?
word1 word2 word3
I am fine
word1 word2 word3
Where've you been?
Real outcome:
Quote:
file1.txt:word1 word2 word3
how are you?
--
file222.txt:word1 word2 word3
I am fine
--
file342.txt:word1 word2 word3
Where've you been?
How may I remove file*** expression with grep?

Thanks in advance
Boris

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
