Yes, Jerry they are a predominately accapella group with some numbers they use jazz accompaniment. I will find you a site where you can hear a sample when I get a minute. Glen, sorry that I have managed to pull the thread to other than the 4 lads. One of my fond memories when I was in college in the mid 60's was a group called the 4 saints. These guys were versitile in singing and use of various instruments, sometimes switching in mid song from 4 part vocal harmony to 4 trumpets! Terrific in a small area of the midwest, but alas, never any significant national commercial appeal. anyone heard of them?
