The artists you mentioned sound good, but you probably should mix in modern stuff, otherwise the parents may enjoy the show more than the grads. These groups/songs made the top 100 in 2004: Maroon 5 [This Love], lots of new U2 and Green Day, Jet [Are You Gonna Be My Girl], Blink 182, Switchfoot [Meant to Live], Couting Crows [Accidentally in Love], etc.
The Beatles, Zepplin, and CCR may be recognizable, but blues isn't that popular with kids.
Here are links to the 2004 and current top 100 charts. There are a good number of rock songs listed, especially in the current one.:
