Beechwood hit #10 in New Zealand, so for an Oceania album it was probably included for that.Yes, 'Calling Occupants' had been the biggest hit in Australia since 'Only Yesterday', nearly three years before.
'Calling Occupants' peaked at Number 13 nationally but would have peaked higher if it hadn't taken off in different states at totally different times. For instance, in South Australia, (a state of Australia), it peaked at Number 5 in mid-January, 1978, whereas in Victoria, (another state), it didn't enter the charts until mid-March, 1978, eventually peaking at Number 10. In New South Wales, (where Sydney is), I think it peaked at Number 9, from memory, but I can't find anything at the moment to double-check. I'm not sure about the other states.
'Calling Occupants' hung around nationally long enough to become the 78th biggest hit of the year, eventually spending over seven months on the charts.
'Passage' had a similar story, peaking near the Top 10 in different states, but at different times.
'Very Best of The Carpenters' includes 'Beechwood' and 'Those Good Old Dreams', from 'Made in America', which was still a recent album, ('Made in America' mid-1981, 'Very Best Of' late 1982). Interestingly, no 'Touch Me When We're Dancing' on 'Very Best of The Carpenters' and no 'Want You Back in My Life Again' or 'I Believe You'. 'Touch Me When We're Dancing' only peaked at Number 78. 'Those Good Old Dreams' received some airplay, daily on some radio stations, and the video for 'Beechwood' received airings on some music shows but neither songs charted. 'Beechwood' had a picture cover, which was rare in this record market.
The TV promo for 'Very Best of The Carpenters' showed a snippet of 'Sing', from 'Live at the Budokan', in Japan, amongst snippets of a few other songs.
The promo poster was 36" x 24", showing the inner sleeve from 'Made in America', (which was the cover photo).
But in New Zealand it looks like they only hit the charts starting with Postman (#4) in May 1975. And TMWWD was their lowest charting at #22, otherwise the couple of other charting Singles were Top 20.
