I realize you could all be somewhere else now, so thank you for being here. It won't look, sound or feel like you. Be yourself, not a script. The point of the above samples is your asking two questions to get everybody's attention in mind and body.

Most introductions are about the speaker.
If you really want the listeners' attention, ask about them. Vary your process and be yourself. Ask but I really expect you to develop your own.
