Swing music and big bands were over by the mid 40s, so you can't blame the Beatles for that.I'd say yes.....but then again, just like Nirvana came along and put an end to hair metal (bastards!! :cussing the Beatles probably put an end to...... swing and big bands. Now instead of having a whole ensemble of musicians playing just about every instrument, you had four guys with guitar, bass, and drums for the rhythm. So, of course, the Beatles were probably the only altarnative for young people who weren't ready to look like their parents.
