Start with a clean grill. Keep it clean by brushing with a wire brush after preheating and again after cooking. Make sure to oil your grates and your food before putting it on the grill to keep it from sticking.
The greatest thing about doing this movie was that Chris and I both were involved in folk music in the '60s. I had a group but I don't think it was at the same level as Chris because he's an amazing musician.
