I was intending to record the responses for Low Mass to help out altar boys who wish to learn them. Thankfully, this has already been done (thanks to Fr Zuhlsdorf for the link.) This recording was made in the 1950s by the Catholic University in Washington D.C. It was originally made for an LP record.
The introduction in the sound file is good and boys would do well to listen to it. They may then wish simply to go back to the prayers at the foot of the altar to learn them thoroughly. The prayers of the Mass begin at about three minutes in. The other more difficult response which boys may need to listen to several times is the Suscipiat. This can be found at 09.22.
To download a copy of the file for your mp3 player, iPod, smartphone or other device, go to the Internet Archive page or simply right-click on this link and choose "save link as" or "save target as", depending on your browser. (You will need to unzip the file once you have saved it.) Then you can put it on your mobile device and listen to it from time to time on a journey.
