Just tried this one last night on some angus tips and it was awesome. Here we go

1 cup Italian dressing
1 cup Barbecue sauce
1/2 cup worcestire sauce
2 tables spoons garlic pepper seasoning

Marinate the meat for a coulpe hours. I did mine for about 45 minutes and it was good. I think this stuff would be better left to set for a bit. Try it and let me know what you think.
