The brass overdubs for Suspicious Minds only exist on the final mono and stereo masters, and the mono and stereo masters both have different brass performances. According to Bill Porter, the reason for this procedure was that all the 8 tracks were full. Porter also persuaded Felton to do the final stereo and mono mixes at the same time as this overdub session. This is also the reason why both the remastered attempts 'Memphis Record'(1987, missing the brass) and '30 #1 Hits'(2002, flanging due to mixing stereo master with 8-track) failed. Remastering Suspicious Minds must involve faithful re-recording of the brass section. Maybe that even can be justified now that there is no clear definition of "original" master in the first place.
