Does anyone own a cd of Solesmes called Fête-Dieu (Corpus Christi)?

I am asking this because I recently bought many of those old remastered Solesmes recordings. Despite being very old, they sound great but my copy of that particular recording, on the track "Litany of Saints", the volume keeps decreasing during the chant. So I wonder if I have a faulty cd or in other copies of this same recording this also happens.
