2 Years On is a 1970 album released by the Bee Gees, which reached No. 32 on the US charts, and sold 375,000 copies worldwide. The album saw the return of Robin Gibb to the group after an earlier disagreement and subsequent split following Odessa. 2 Years On was the first album with drummer Geoff Bridgford, who remained a full-time member of the group until 1972 although he was not pictured on the sleeve. The best-known track is "Lonely Days". Released as the first single by the reunited brothers, it charted high in the US (No. 3 on the Billboard Hot 100 and No. 1 on the rival chart Cashbox), but peaked at No. 33 in the United Kingdom.
