Grease, it truly is one of the best musicals ever invented. If you’re anything like us, you watched it over and over as a teenager, in the hope that Danny Zuko and a pack of loyal Pink Ladies would materialise at your front door. John Travolta, the original Danny turns 60 today, and in tribute to the leather-clad hip-shaking muscle man himself, we have put together some of Grease’s best moments. The T-Birds This just had to be number one. Muscly men, lots of leather and one very catchy tune. “This car could be systematic”… you know the rest! http://www.youtube.com/watch?v=wK63eUyk-iM Frenchie is Our Favourite We all need a friend like Frenchie. Always there to offer advice and when things go wrong, this Pink Lady offers a shoulder to cry on. Plus, there is ALWAYS gum when Frenchie is around. Hopelessly Devoted Sandy singing her heart out about a boy is something we can all relate to. Ok, maybe not the singing but definitely the pain of a first heartbreak. The first cut is the deepest and all that craic… we feel your pain Sandy, we do. The Original Smoulder Any Tangled fans out there will be familiar with Flynn Rider’s ‘smoulder’ but Danny Zuko can be credited with the original smouldering look. Weak at the knees, weak. The Moves There is SO much dancing in this film, and everyone knows the moves. Even your Dad has Greased Lighting down to a T, (thinking he's the ultimate T-Bird). From the prom to the many musical numbers, it’s fantastically cheesy. Just look at them go. Sandra D Much like Frenchie, we could all do with a friend like Rizzo too. She’s well able to have a joke (even if it's a little upsetting for the person in question) but if someone else tries to hurt you, she gets straight in there to fight your corner. Summer Nights This song reminds us of everything good about summer: having the laugh with friends, lazy days, long evenings and sunshine to boot (if you live anywhere other than Ireland that is, but let’s not dwell on that part). http://www.youtube.com/watch?v=P8orR1oK6Kk Sandy’s Makeover Definitely one of the best transformations in film history. Good girl Sandy comes over all vampy vixen and Danny doesn’t know what to do with himself. It’s just too good. Pink Ladies A group of girls who have their own signature style, this is what being part of the ‘it’ group was all about. No one would dare mess with them and they are quite literally, too cool for school.  The Finale  We love every single song in Grease but 'We Go Together' is in its own league of epic. You know how it goes, sing along at the top of your voice even if some of the lyrics are a little questionable... "Shoo-bop sha wadda wadda yippity boom de boom." http://www.youtube.com/watch?v=0pyA6jAM3_I
