Many people in Eretz Yisroel are not acquainted with the words which accompany Western popular tunes and this sometimes leads to undesirable results. About twenty years ago I listened to a computer teaching aid for Gemara. It was accompanied by tunes. But what were many of the tunes? Christmas carols!!! Amongst the worshippers of the shul at which I daven there are a number of Anglo-Saxsons, and in the same building there is also a Talmud Torah. Throughout the day, a bell, which is a collection of tunes, rings to signal the beginning and end of lessons and it can clearly be heard even in the shul. The words of some of these tunes are close to pritsus. One year they forgot to turn off the bell for Yom Kippur. Oshamnu, bogadnu .... with the accompaniment of these tunes!!!
