50's looking rock n roll fonts! please ID!

i saw these vintage looking fonts on some flyers, especially keen to know what 'the sigma' and 'rock' are, can anyone ID them for me?


In Person
The Sigma
The Metros


oh sorry, theres also this one....

"Metros" is Brush Script (should be on your system if you're running Windows). For "THE SIGMA" you can look at House's Sign Painter Font Kit for similar fonts.

THE SIGMA looks like another sighting of Komika Poster by Apostrophic Labs.

Speedy Marker font looks like SIGMA but a little diferent.
