How can I combine objects in the Raphael javascript library?

Sorry for a long question but here goes. I am trying to modify the drag shapes around demo here:

http://raphaeljs.com/graffle.html

The demo works fine. What I want to do is put words inside the shapes and move the shape and text around as a composite single object.

Here is the code for creating the objects:

window.onload = function () {
    var dragger = function () {
        this.ox = this.type == "rect" ? this.attr("x") : this.attr("cx");
        this.oy = this.type == "rect" ? this.attr("y") : this.attr("cy");
        this.animate({"fill-opacity": .2}, 500);
    },
        move = function (dx, dy) {
            var att = this.type == "rect" ? {x: this.ox + dx, y: this.oy + dy} : {cx: this.ox + dx, cy: this.oy + dy};
            this.attr(att);
            for (var i = connections.length; i--;) {
                r.connection(connections[i]);
            }
            r.safari();
        },
        up = function () {
            this.animate({"fill-opacity": 0}, 500);
        },
        r = Raphael("holder", 640, 480),
        connections = [],
        shapes = [  r.ellipse(190, 100, 30, 20),
                    r.rect(290, 80, 60, 40, 10),
                    r.rect(290, 180, 60, 40, 2),
                    r.ellipse(450, 100, 20, 20)
                ];
    for (var i = 0, ii = shapes.length; i < ii; i++) {
        var color = Raphael.getColor();
        shapes[i].attr({fill: color, stroke: color, "fill-opacity": 0, "stroke-width": 2, cursor: "move"});
        shapes[i].drag(move, dragger, up);
    }
    connections.push(r.connection(shapes[0], shapes[1], "#fff"));
    connections.push(r.connection(shapes[1], shapes[2], "#fff", "#fff|5"));
    connections.push(r.connection(shapes[1], shapes[3], "#000", "#fff"));
};

I tried something like this:

 myWords = [ r.text(190, 100,  "Hello"),
      r.text(480,100, "Good Bye")
