Seventh season runner David Archuleta is returning to American Idol on Wednesday night's results show, as one of the guest performers.

Since we'll be tackling (again) the Lennon/McCartney songbook next week, there's no perfect person to tackle that than Archuleta, who performed two Beatles songs during his run on the show: "We Can Work It Out" on Top 12 week and "The Long and Winding Road" on Top 11 week. This Wednesday, he'll be performing John Lennon's classic "Imagine"--a song he also performed during the season 7 semifinals.

Also performing on Wednesday night: Rihanna, who will perform her latest single "Te Amo", and Jason Derulo, who will do "In My Head". I guess that means we won't have another group routine--thankfully, you might say.

Prepping for tomorrow night's performance show? Abbey's used her really (really) wide Beatles knowledge to pick songs the Top 9 should perform. Slideshow's right below!
