After holding out in favor of HD-DVD for a while, Paramount is quickly getting on the blu-ray bandwagon by releasing catalog titles.  Of the latest is one of their flagship titles, Grease starring the multi-talented and oddly charming John Travolta

QUALITY:
Good, for a three decade old movie.  The picture, although slightly color faded, is pretty clear and, more importantly for a musical, the sound is loud and nearly lossless.

BONUS FEATURES:
Sing-Along, featurettes.

There is nothing new here that wasn't on the same DVD released earlier so don't buy this one expecting some amazing "HD blu-ray features", you will be disappointed.  But, if you just want one of the best musicals of all time in the best quality possible, toss your DVD and pick this up, it's certainly worth the upgrade.
