I have this identical item, which I have just entered into the site, with the Cat. Number 2659 012.
Can't find this mentioned anywhere with the 2059 cat number.
The History of Eric Clapton is a compilation double LP, released in March 1972 by Polydor in the United Kingdom and Atco Records in the United States and features Eric Clapton performing in various bands and solo between 1964 and 1970. It is notable for helping both Clapton's career when he was battling a severe heroin addiction and making Clapton's magnum opus, "Layla", famous.
The two "Tell the Truth" tracks here are different to and were recorded before the one on Layla and Other Assorted Love Songs. "Tell the Truth" is a fast up-beat version of the song and was originally released as a single in July 1970. "Tell the Truth - Jam" is a long and slow instrumental jam from the Layla sessions which had never been released before. The version that appears on Layla and Other Assorted Love Songs is a combination of these two takes: the frantic pace of the single is slowed down to the laid-back speed of the instrumental.
