and the beat goes on

Dear All,

Most of you know that [Colleague 1] has accepted a new position [within the organization]. [Colleague 1] has been a key part of our own [work] efforts, and we will miss him terribly. But first, we will have a little party from him, at which we will also congratulate [Colleague 2] on her new position [also within the organization]. We will miss her presence [in her to-be former office], where she has been unfailingly cheerful, helpful, and beautifully dressed.

Please join us [soon], in the [place] to congratulate [them] on their new positions--both of which constitute promotions. We'll have the standard yummy pastries from [the yummy pastry place], and we'll all have an opportunity to thank both [of them] for their excellent work with us.

Best.
