Name Of A Song.?

I heard it at work years ago. 

It was a song where people were singing Welcome in different European languages.

It was like _________ __________Welcome __________ Welcome.

The lines I put to show other languages that were said for Welcome and I can't even begin to spell them. 

As a matter of fact TWA Airlines used the song a commercial in the 80's.

It ended with  "You're Gonna Like Us, TWA TWA TWA.

That of course was their song back them though for the commercial it was sung to sound like the mystery song they were spoofing.
