This is the first UK issue. The main identifiers are: - Outside laminated gatefold sleeve with 'Printed and Made by Garrod & Lofthouse Ltd.' (until about 1981). - Inner sleeve: Copies bought in the first month of release feature a plain inner sleeve with 'Patent Nos. 1125555' text and 'Made In Great Britain' text in BLACK PRINT near the bottom on 1 side. Shortly after this LP was released (about July / August 1970) EMI introduced the 'Harvest' advertising inner sleeve. So with all copies made from this date onwards mostly having the 'Harvest' advertising inner sleeve instead. However, plain EMI inner sleeve were also used; - Runouts: A2 / B1 (until about mid-1975). It is worth noting that variant 1 - 1st pressings with A-1 / B-1 matrixes are extremely rare on this LP. They were changed prior to the release date, with even most release date copies having A2 / B1 matrixes instead. Only 1 in 20 1st pressings have this matrix - with A2 / B1 matrix being used through all remaining 1st pressings, and many 2nd pressings also; - The upper rim text begins with 'THE GRAMOPHONE CO LTD.' (until about May 1974); - No 'EMI' logo on labels (until about June 1971); - The inscription 'MADE IN GT. BRITAIN' on labels is separated of the lower rim text and centered above the circular bottom line (until about May 1974); - Song listing in 3-lines for side A and in 4 lines for side B (until about the second half of 1972); - The Ⓟ icon (under the 'Side A/B' indicator on labels) is about a third smaller than the year '1970' to the right of it (until about December 1970 / January 1971); - Inscriptions (on the right side of the label) 'STEREO', 'SHVL 777' and '(SHVL.777A or B) 33 1/3' are located one above the other and have an equal gap between them. Recording Studios: IBC: Tracks A1, A3, B2, B3. Abbey Road: Track A2. De Lane Lea: Tracks B1, B4. ℗ 1970 Runouts are stamped.

This is 1976 - 1980 UK reissue.

Actually there are practically no any obvious visual differences between 1976 - 1980 pressings, except insignificant color variations in label background shades of yellow, which vary from yellow-green to lemon-yellow and the figurate sections (incl. logo and the rim text) which vary from green to dark green or even shades of blue.

The pressing year could be approximated by date codes indicated on the inner sleeves.

The main difference from the previous issues:

1) Runouts: A4 / B3. A new master for Side A (A-4) was used for these reissues. The master again was cut by

Other main identifiers:

- Laminated gatefold sleeve with 'Printed and Made by Garrod & Lofthouse Ltd.' in most cases have an additional keyline box around the EMI and Harvest logos on the front of the sleeve. But the 1st sleeve variant with a single bold line around the logos is still valid.

- Inner sleeve:

a) EMI inner sleeve with 'Care Of Your Record' box high centre, 'Important Notice' box in low centre and 'Made In Great Britain' above 'Patent Nos. 1125555' near the bottom (since about late 1974 to 1978);

b) EMI inner sleeve with 'Care Of Your Record' box high centre, 'Important Notice' box in low centre and 'Made In Great Britain' above 'Patent Nos. 1125555' with date code near the bottom (since about 1978 to 1980);

c) EMI inner sleeve with 'Care Of Your Record' box high centre, 'Thinking of giving someone a record as a gift?' bubble mid centre, 'Important Notice' box in low centre, 'Made In Great Britain' above 'Patent Nos. 1125555' and with date code near the bottom (since about 1980 to 1982);

- The upper rim text begins with 'EMI RECORDS LTD.' (since about May 1974);

-The inscription 'MADE IN GT. BRITAIN' is inlined with the lower rim text (at the end) under the circular bottom line (since about May 1974 to about 1981);

- Runouts: A4 / B3 (since about 1976 to 1980);

- The boxed 'EMI' logo on labels (since about June 1971);

- Song listing in 2 lines on both sides (since about the second half of 1972);

- The Ⓟ icon (under the 'Side A/B' indicator on labels) is the same size as the year '1970' to the right of it (since about December 1970 / January 1971).
