Name of the songs spoofed by a Swedish programme

I was going to find an intro of SVT Rapport on YouTube. I choose one of results. And an eye-and-ear-catching trailer of Doobidoo made me laugh.

http://www.youtube.com/watch?v=uNRHRzcEzCI (Full trailer located at around 6:08 but also has a-few-seconds-missing trailer at the beginning.)

And now I wonder, what were the songs got spoofed. (Although I can recognise last part is "All we hear is Radio Ga-Ga"- Radio Ga-Ga by Queen.)

I love Doobidoo! Never thought I'd see a reference to it here. As for the songs, the Kiss-style one is "I Was Made For Loving You", not sure about the rasta one though.

I assume the Bob Marley-style one is Jammin', and the very very last second of the trail will be taken straight from Diggiloo Diggiley.

Also, is that one of the guys from Triple och Touch?

Found an official site for Doobidoo today ( http://svt.se/svt/jsp/Crosslink.jsp?d=94995 ) and 4 full videos of parodies.

Robbie Williams: http://svt.se/svt/play/video.jsp?a=1216871 < THE REMAINING ONE. What is the original song?
KISS: http://svt.se/svt/play/video.jsp?a=1216870
Bob Marley: http://svt.se/svt/play/video.jsp?a=1216873
Freddie Mercury (Queen): http://svt.se/svt/play/video.jsp?a=1216866

"Let Me Entertain You".

Thank you so Much!!!
