My kids (who are 30) know who Ringo Starr is - he's the conductor on "Shining Time Station" who introduces Thomas the Tank Engine animations. They don't know what his real name is, and really see no reference to music in the question. Actually, they were a bit old for Thomas when the series came out, so they think Ringo's pretty lame. My kids have heard Beatles' music, much as I heard big band - old folks play it all the time. Some of it they even like, but they're just now beginning to admit it.
