The Spice Girls reunited on Tuesday to discuss Viva Forever, a West End-bound musical that will reportedly showcase a revival their greatest hits.  

Produced by Judy Craymer, who also happens to be the mastermind behind the international sensation Mama Mia, the musical is loosely based on the girl group's rise to fame - but the girl group at the center of the show are launched to stardom via reality T.V. The show will debut in London on December 11. 2012.

Further details have yet to emerge about the show, but the Spice Girls offered their advance praise in an interview with the Associated Press. It's better than we could ever have imagined, said Melanie Chisholmm aka Sporty Spice. They sing it better than us, added Melanie Scary Spice Brown.

We dug through our old CD collection to determine which girl power songs should make the cut.  Here are five Spice Girl hits we hope will appear in Viva Forever.

5. Viva Forever

We think there's a pretty good chance audiences at Viva Forever will hear Viva Forever. The title track for the upcoming musical demonstrates the group's surprising vocal range. The touching tune combines a wide range of instruments such as the Spanish guitar. The single, which conveys feelings of painful nostalgia, was released not long after Geri Halliwell left the group (though recorded during happier times.)

Reception: The song became the group's final single featuring Halliwell to reach number 1 in the UK. Though it climbed several European music charts, it was not released as a U.S. single.

Interesting Fact: The song's music video features five fairy puppets modeled after each of the group members. By the time the video premiered, the band was down to four members and the record label was scrabbling to salvage the Spice Girl brand.

4. Mama

Mama, is a beautifully written ballad in which the group thanks their mothers for supporting and loving them through the years. It also touches on the difficulties that inevitably arise within mother/daughter relationships.

Reception: The song debut at number 1 in the UK and was a massive hit throughout the world. It was not released as a single in the U.S, but appeared on the album Spice.

Interesting Fact: In his review of Spice for Entertainment Weekly, Ken Tucker wrote that the song would keep them from being one-hit wonders in America.

3. Spice Up Your Life

The first single off of their second album Spice World, the electro/pop fusion combines elements of salsa and a variety of Latin genres. A global dance anthem, the song also factored heavily into the promotional campaign for their film Spice World. The band performed the song at notable music events throughout the world, such as the European Music Awards.

Reception: In the UK, the track became their 5th number one single, making them the country's first band to have their first five singles reach number one. However, the single was a relative failure in the U.S, barely cracking the top 20.

Fun Fact: The song served as the opening number for their 2008 reunion tour, The Return of the Spice Girls.   

2. Wannabe

The band's breakout hit, Wannabe made it clear that the Spice Girls represented friendship and girl power. Sure some of the lyrics don't make sense (what exactly is a zig-a-zig-ah?) but the catchy track is the true embodiment of 90's pop. The song's lyric conveys the importance of female friendship over male companionship.

Reception: The song was a platinum smash hit in the UK and subsequently climbed the Billboard Hot 100 charts in the U.S. 

Interesting Fact: Despite the band's success in the U.S, Wanabe is their only single to reach number 1.

1. Goodbye

Perhaps the most bittersweet song in the band's catalogue, Goodbye was recorded after Geri Ginger Spice Halliwell left the group in 1998. In the ballad,  the four remaining members expresstheir acceptance of Halliwell's departure and wish her well. The song was included on the finale Spice Girls album. In many ways it symbolizes the end of an era. 

Reception: The song marked their 18th number 1 single in the UK.  It had a less successful run in the U.S, never breaking the top 10 on the billboard charts.

Interesting Fact: During their reunion tour in 2007, Halliwell sang the song with the rest of the group.
