The shortest track on the 10 track album Tabernakel is the second track Coranto for Mrs Murcott (1:26") and the longest, the final suite, Lammy (14' 06").
The other solo lute tracks range from between 1' 31" and 3' 17" in length with House of the King at 2' 23", Javeh at 3' 22" and Britannia at 3' 55".
The original first side lasted 20' 26" and the second side a shorter 17' 23". That is a total length of 37' 49" and so it takes about 40 minutes to listen to. Originally LPs could only comfortably manage 23 minutes a side maximum. The album is fairly typical in terms of length then.
