Premiere: Make music sound like it's coming from huge speakers? The problem with my clip:

It was recorded on a fashion show and my recording for some reason stopped, but I quickly restarted it, so approximately 2 seconds are missing. On the visuals, not much was happening at that moment, so a cut is not that noticable luckily.

BUT: music was playing in the background, so it doesn't matter how I cut, in the audio, you obviously hear the cut. My solution for this problem is to download the original song, bring it to Premiere, put it in place between/under the 2 pieces of clip.

QUESTION:
I need this audio to sound like it was recorded "on-set", like the song was played on a huge speaker in a 10m x 20m hall. I tried the audio effect highpass, but with that, it sounds like it was played on a phone, since it eliminates lower frequencies. I tried a few other filters, but since I'm not really into that topic, I couldn't make it convincing.

Thanks for the help.
I've had good luck by sampling a bit of the video's audio from another point, and splicing that in.  The tone will be dead-on consistent.  You just have to find a point in the song where it basically repeats itself (or close enough).  If you lost verse lyrics, this gets much more problematic fast.  But if you lost chorus, or instrumental bridge, intro, or outro, you could make a patch that manages to not distract.  It the song was well-known, a forced splice will be more evident, but might not seem your doing (you know?).  At the other extreme, if the song is house music, you're golden: no one will know what it was supposed to do for those two seconds.
