help with combing intro and song

Hello all,
I am new to the Audacity program and do not have the foggiest idea what I’m doing. I am trying to combine the intro ( In the beginning-Motley Crue ) to the song Shout at the devil-Motley Crue so that will play as one song. Any really easy to follow directions would be greatly appreciated !!

Audacity’s spectrogram-view is useful when beat-matching

A cross-fade may be required.
