How to say thank you as a prelude to a treat?

The opening remarks are as follows:

1. I feel very honored that everyone took the time to have dinner here. Thank you all for your help and support in my daily life. I feel very happy to have a chance to gather together today. Come on, let’s all have a drink first.

2. It’s really rare to have such an opportunity to have a dinner together today. Everyone is usually very busy at work. Since we have a chance to get together today, we will eat and drink together. I’ll treat you. Don't be polite to me.

3. Thank you to your relatives, friends and fellow villagers for taking the time to come to xxxx. If there is nothing delicious to eat today, I will invite you to have a few more drinks.

4. I will leave immediately to work (study) in another city. I don’t know when I will come back. I’m just treating you all to a casual meal today. Please help me take care of my family during my absence. Thank you all for coming to dinner today. Feel free to do whatever you want!

5. I am very happy today. So many friends are here. Usually everyone is too busy to get together. Since we have the opportunity today, let’s eat and drink. Come on, I'll do it first as a courtesy.
