Well I have to say I am underwhelmed by the response.
Answers in bold
1). If she finds Out -
The Twilights (Glen Shorrock pre Axiom and LRB and Terry Britten pre making millions writing songs for Cliff Richard)
2). Undecided -
The Masters Apprentices (As pointed out by Mcalmanac)
3). 1X2X3X4 -
The Zoot (Beeb Birtles pre LRB and Daryl Cotton pre the RSL circuit)
4). Seasons of Change -
Fraternity (Doing a Blackfeather song - Bon Scott post Valentines and pre AC/DC)
5). Keep on Dancin' -
The Keystone Angels (Pre - The Angels when they flirted with the idea of being a Glam Rock band. Complete with long hair, satin shirts and flares)
6). Best deal in town -
Scandal Flogged to death on 5AD and 5KA in the mid 70's. Had one other minor hit with "How Long" and then disappeared - thankfully
7). Quick on the draw -
The Stars (As picked out by Kahuna). - Country Rock in flares by Middle Class Adelaide boys in the mid 70's - "Oh what a decade"
(McAlmanac got both of the above. Anyone would think you and I were the same age!

)
8 ) . Main Street -
Redeye - Awful song with equally awful filmclip (filmed down the quiet end of Hindley St). For some unknown reason the song was flogged to death on 5AD and the video on Sounds.
9). Ten Years On -
The Dagoes - As picked up by CedeNullis. One the greatest Adelaide bands of all time. Johnny Tomato is now a lawyer in Sydney.
10). Let's get pissed -
The Innocents - Great punk band from the early 80's. Johnny Cav went onto the Screaming Believers.
11). Baby you flirt -
The Units - The great white hope of the Adelaide alternative scene in the early 80's. Sadly disappeared after one single. They did support AC/DC on their Back in Black tour at Memorial Drive though.
12). I just want my fun -
The Exploding White Mice - Bigger in Holland than they are in Australia. Great band despite Dave Bunney following a crap footy team.
13). Bite the Bullet -
Just Kidding - Adelaide's top ska band of the 80's. And Chris Mills wins the best hairstyle in Adelaide in the 80's competition.
14). She gets me -
Lizard Train - (Well done Booney) Great song by a great band. Came out in 1990 and should have been a huge hit. Alas it wasn't
15). Tell me -
The Mark of Cain - Once again well done CedeNullis and Booney. These guys are still going and I for one can't wait to see them in January at the Corner Hotel.
