Better late than never - I wanted to be sure to post a link here to the entry on my parish's Catholic blog, from last Sunday's Corpus Christi solemn Mass and Eucharistic Procession.  On the post (provided it loads for you... blogger has been so iffy lately) you will see some pics from the procession and a whole plethora of mp3s from the Mass, including part of the sequence, Lauda Sion.  Why only part, you may wonder? Well, for one it is awfully long to just sit and listen to at your desk, but for another I started a little bit too low and the whole first part is kind of growly.  It got better later, and toward the end a couple other ladies jumped in on the Ecce Panis Angelorum part, which they had learned last year in my little schola. 

By the way, it was kind of up to me about doing the long version vs. the short version.  I knew our pastor had asked my father to read the whole sequence at another Mass where it was not being sung.  I can understand why... St. Thomas' text is quite powerful and intensely catechetical.  It is not very "PC" if you know what I mean.  Here is some of it in English, with translations from the Gregorian Missal:

The good and the guilty may all have part therein,
but with different results:
life or death.

Death for sinners, life everlasting for the just;
mark well the varied effects
of this single food. 

So even though I doubt anyone (excepting our pastor) would understand the words in Latin, the congregation did have access to the translation in the missalettes, so if they wanted to read through the English version while the Latin was chanted, they had plenty of time to do so. 

I included some audios from the rest of the Mass music on the parish blog as well.  You'll be able to hear Panis Angelicus and Tantum Ergo, as well as an organ postlude.  For anyone who has not visited our parish, this will give you a little taste of what it's like at St. Peter's.  Now come in person!
