Define Irony

Isn't it ironic that Lynyrd Skynyrd (fronted by Kid Rock) performed "Sweet Home Alabama" while sharing the MTV React Now telethon bill with Neil Young?

For those who've never sung along with the song (or only know it from Bo Bice's rendition), its lyrics include the lines:

Well, I heard Mister Young sing about her
Well, I heard ole Neil put her down.
Well, I hope Neil Young will remember
a southern man don't need him around anyhow.

Of course, right now, a southern man needs all the help he can get.

And maybe the pairing up is only as ironic as rain on your wedding day, as this site offers an interesting history of the song and those lines.
