I should have thought a little longer. :'-(

Found something that works:
ffmpeg -ss 308 -t 4 -i 00011-00016.MTS -ss 329 -to 374 -i 00011-00016.MTS -pix_fmt yuv420p -vcodec libx264 -crf 26 -acodec libmp3lame -qscale:a 9 -preset veryfast -filter_complex '
    [0:v][1:v] xfade=transition=hlslice:
                     duration=4:
                     offset=0                                                   [v01];
    [0:a][1:a] acrossfade=d=4                                                   [a01];
    [v01]      drawtext=
                   box        = 1:
                   boxborderw = 6:
                   boxcolor   = black at 0.2:
                   fontcolor  = white at 0.4:
                   fontfile   = FreeSerifBold.ttf:
                   fontsize   = 32:
                   text       = © 2022 Cecil Westerhof - Cecil at Decebal.nl:
                   x          = ((main_w - text_w) / 2):
                   y          = main_h - (text_h * 2)                           [v02]
         ' -map '[v02]' -map '[a01]' xfadeMusicalTestTemp/accordeonmuziek.ts


It looks and sounds OK to me. But I do get:
