Bit of trivia: Luke's squadron in the movie was supposed to be Blue Squadron, but since that didn't do too well with the bluescreen(or maybe it was a greenscreen? I can't keep them straight) it got changed last minute to Red. Supplementary material tells us that there was a Blue Squadron at the Battle of Yavin and it got pretty much decimated. I think Keyan Farlander - that was the surviving Y-Wing - was in it.
A recent comic shows that Red Leader did fly with Anakin Skywalker briefly, during one battle of the Clone Wars. It's somewhere on the wiki.
