I shudder when I think of Beat Club performances. All except maybe a very few, were mimed and just featured tracks lifted from albums with some overdubs to make them sound "live". So if you want to see T Rex on a small stage miming to album tracks, then go ahead. Otherwise get Bolan on video elsewhere and buy Spaceball to hear solo acoustic Bolan.
With few T. Rex DVD's available, this "Enhanced CD" with cd Rom capabilities is a great edition. It gives Bolan fans an opportunity to see T.Rex as well as hear them Live. Though the material was taped for German TV in the early 70's, and isn't of todays quality and contains some overdubs, it's great to see & hear, especially Buick MacKane. I've seen hundreds of the top rock bands & musicians live, but the magic of T. Rex was something special. Gone, but not forgotten.
