Ah-ha ..ok think I've got it thanks

I was thinking along those lines & before I got your reply had decided to do a 'tap-along' count from the full performance & see if it matched approx 72 in a minute. Out of interest I tried it anyway. Tthe first count was off but maybe due to the intro or me. On the second (midway through the song) go pretty close 72 taps in 56 seconds.

I had indeed at first been focusing on the strums.

Thanks for the help.
